Urban Planning for Tertiary Cities

With the era of the raging pandemic, peaceful and more comfortable living arrangements became a priority for many. Large primary and secondary metropolitan cities are moving away from the spotlight as smaller, less developed and more affordable tertiary cities gain popularity as a residential option. This article explores the opportunities tertiary cities offer to residents, communities, and organisations, and how conscious planning can contribute to their sustainable future.

What are tertiary cities?

Typically, tertiary cities are smaller cities with more affordable housing alternatives but limited infrastructure and less investment. This article provides successful examples of tertiary cities with a common denominator of steady expansion, growing economic activity and an innovative approach to sustainable planning.

The Urban Planning Challenges of Tertiary Cities

The expanding tertiary cities must employ urban planning strategies for a steady flow of investment without infringing on the original and emerging new lifestyles of its residents. The main concerns are, therefore:

  • How to provide inclusive new development with a healthy combination of economic, environmental, and social aspects?
  • How to maintain equal housing opportunities and moderate rent prices?
  • How to promote sustainable economic activity?

Here are some examples of how tertiary cities address these challenges and increase their benefitting potential at various stages of development through great planning solutions.

Functional Transformation | Gorlitz, Germany (56,000 inhabitants)

Collecting information and data provides an opportunity to better target potential new residents and investors and contribute to the city development.

Gorlitz is a tertiary city facing negative demographic tendencies. However, it has realised its great potential as a residential area. It mostly attracts people seeking more affordable housing options than in the big cities while retaining an urban lifestyle. The city benefits from its convenient location and infrastructure and the uniqueness of the historic building stock.

To better determine the target groups of the residential development in the city, a scheme called ‘Stadt auf Probe – Wohnen und Arbeiten in Görlitz’  –‘City Trial – Living and working in Gorlitz’ has been realised. It offered potential incomers an opportunity to live and work in some of the available building stock in the city for 4 weeks to ensure that further planning could be based on the data collected. This way respective housing typologies could be proposed ensuring steady growth and sustainability of the solutions transforming the city into a residential hub.

According to the study, the city is mainly attracting big city residents, which may be interested in its calmness, well-maintained public space and abundance of accessible green areas. However, it has also demonstrated that this type of tertiary city can also attract residents from much smaller towns and the country seeking a certain type of urban lifestyle.

Planning for Diversity | Newhall, Harlow: A New Garden City, UK (81,944 inhabitants)

The priority of the Newhall development was the diversity and liveability of the spaces; therefore, it has employed a very distinctive design strategy. The principles of this are in The Book of Newhall’, which acts like a manifesto providing guidelines and requirements for the developers to explore new diverse typologies of housing.

The whole development had been divided into smaller plots put to tender to ensure the engagement of different architects and developers. This approach brings a lot of value through the variety of architectural styles and different identities. Furthermore, functional variety has not been left aside. An active street edge was formed by the commercial units on the ground floor and the rest of the spaces were occupied by the units for living and working.

Finally, an important factor in this development was also the active participation and engagement of landowners. They were involved in the planning and development process and chose a long-term approach to increase the site value.

A combination of actions promoting a vibrant development of the city can contribute to its sustainable growth and maintain its attractiveness.

Community Structure and Framework | Culemborg, Netherlands (29,386 inhabitants)

EVA Lanxmeer is a development in the Dutch city of Culemborg introducing new types of ownership structures for housing. It brings along new possibilities in terms of property rights and responsibilities adding to the overall sustainability of the scheme. The property owners officially form a foundation which formally outlines their goals, rights and responsibilities leading to a sustainable future. By purchasing a property in this development, inhabitants commit to following the rules such as minimal use of energy, fossil fuels, reuse and recycling, minimal use of cars, active participation in social activities and maintenance of public space.

EVA Lanxmeer represents how small-scale tertiary cities could be planned and managed to ensure sustainable growth and maintenance employing different relationships between the stakeholders, e.g. developers, property holders and municipality.

Learning and Participations | Gelsenkirchen, Germany (260,654 inhabitants)

The participation of the general inhabitants of the city in the planning is essential for an integrated urban development successful example of which is the former area of a coal mine, Gelsenkirchen.

The district had suffered out-migration, unemployment, and high vacancy levels in the past. However, it has since been transformed and accommodates various new functions and a city focused on learning. To promote participation and integration of citizens in the city planning and decision-making process, the city provides educational opportunities for all demographic groups, from small children to adults. Thanks to the involvement of the city residents and targeted financial support of the local economy, the whole district has been revitalised.

A combination of a formal participatory process with informal cooperation of citizens, associations and businesses can also prove valuable in planning for the emerging tertiary city economies and revitalising stagnating or deteriorating ones.

Benefitting from the Natural Potential | Győr, Hungary (130,000 inhabitants)

With lower density, tertiary cities can benefit from their nature-based potential in energy generation and sustainable development, preserving the quality of urban living.

Gyor represents good example of a city strained by rapid development. Its main challenges stem from the industrial development and the construction of new residential areas. Due to this, growing traffic, loss of farmlands to grey infrastructure, increasing waste production, and air quality deterioration threaten the city. Therefore, a series of interactive events, workshops, awareness-raising campaigns and meetings took place in Gyor, aiming to develop the local Structural Plan. The ’smart city’ program started in the city enables the collaboration of large utility companies with local governments and universities to benefit from its natural assets.

Why Deforestation Is Not Always Bad

Forests represent the green lungs of Europe. They can provide an essential resource not only at an ecological level but also at an economic level. The interest among the European community in wooded areas has grown dramatically in recent years, partly due to the contentious issue of global warming. This article sets out an argument for controlled “deforestation”, as an important maintenance tool for the health and vitality of forests. We also present a series of solutions to the issue of uncontrolled forest expansion in order to preserve the forest flora and fauna while encouraging close contact with our environment in order to develop a sustainable rural sector.

Forest as Both Land Use and Habitat

Europe’s forests span 182 million hectares or 5% of the world’s forest area. They cover 43% of the EU’s land area and contribute significantly to reducing CO2 levels, preserving biodiversity, and producing wood, fruit, and game. Nationally, their importance varies considerably. For example, Forests cover 60% of the total land area in Finland. While in the Netherlands, forests only account for 11% of land coverage. Contrary to many regions of the world where deforestation continues to be a serious problem, the land area covered by forests in the European Union has grown considerably over the past 10 years, thanks to natural succession. The EU has General Guidelines for the Sustainable Management of Forests in Europe, which can be a useful in-depth study on the subject.

Exponential Growth of Forests Due to Rural Decline

The many types of forests in the EU reflect its geo-climatic diversity, range in climates, soil typologies, altitude, and topography. Currently, only 4% of forests in the EU are pristine and have not been modified by man (see for example the Białowieża forest, in Poland). 8% of forests consist of controlled plantations, while the rest (more than 80%) are considered “semi-natural” forests. Furthermore, in most cases, European forests belong to private owners (around 60% in terms of area, compared to 40% of publicly owned forests). This data is significant because a balanced forest control is identified, but is this always the case?

As highlighted in the data above, exponential growth is taking place in a natural and diversified way and not all nations belonging to the European community have the same controlled forest area. In Italy, for example, in the last 5 years, forests have increased by 270 thousand hectares, coming to occupy 40% of the national surface, representing an increase of 75% in the last century. This is largely due to the abandonment of rural areas where natural succession leads to the establishment of the forest as the climax vegetation. Another alarming factor is the variable of climate change. Very strong heatwaves, particularly in western Europe, have led to a great drought in the woods. The lack of water makes the woods deteriorate and exposes them to pests and fire. This also creates an evident displacement of forests in defense of climate change, which unfortunately find it difficult to follow, and this exponential growth will not last long for obvious reasons of space.

So Why Talk About Deforestation?

Controlled deforestation can be a management tool for the wellbeing of the ecosystem, to create new spaces where the forest is not healthy or improperly grown, or where invasive species prevail. This managed approach aims to bring the ecosystem back to a primordial state. There are various solutions tested over the years by various European countries:

  • Programmed Forestry, as suggested by the new EU biodiversity strategy. The advantage is to take possession of the areas around inhabited cities, mitigate Heat Waves in highly urbanized areas, and mitigate the emission of CO2. Bringing new ecosystems into cities can also be beneficial to the implementation of social and citizen well-being. For example, Stefano Boeri’s architectural Vertical Forests. The disadvantage is that not all the towns of the community are able to produce the same amount of wood in a controlled way, and over the years, it could be a double-edged sword for the rapid intensification of vegetation production.

  • Rewilding, a natural solution to the problem. Starting from the general definition that would treat large artificialized ecosystems through actions that put the ecosystem itself in the conditions to then evolve autonomously without the need for further management interventions. These self-willed landscapes recreate the conditions as similar as possible to primeval forests. An important element of this technique is the relationship between the landscape and its fauna. The success of the latter is a determining factor in the maintenance of the former. One famous example of this model is Yellowstone National Park, in the USA. The risk of this method, in addition to having quite slow timing, is the possible public perception of going back and not having control of those areas. However, by reporting upon a more moderate environmental approach in terms of biodiversity, we could act even more easily in case of need.

  • The development of the Bioeconomy and the multifunctionality of EU forests play a key role. The diversity of the latter represents the basis of multiple products and economic, environmental, cultural, and representative benefits of the Circular Economy, contributing to the quality of life today. The development of the bioeconomy of forests is important for each country because the latter have most of our renewable resources and energy, thus responding to the growing demand for biomass such as, for example, in Finland with Finish Forest Industries, one of the nations that make the Bioeconomy a cornerstone, thus bringing to the fore competitiveness and reactivation of rural areas and the abandonment of fossil fuels. A competitive forestry sector provides the maintenance of dynamic yet controlled rural areas and great shelter against land abandonment. Consequently, the maintenance of these functions, including clear-felling, is essential to ensure the stability, sustainability, and controlled productivity of the forest.

A Way Forward

The issue of forest maintenance is at the center of a major European debate. Obviously, there is no one answer or correct way. What emerges is that there are nations facing more difficulty than others in terms of territorial and climatic change. The European community is allocating several billion in favor of the nations most in difficulty, however, we should pause to understand the different needs of the latter, from an increase in the bioeconomy to the preservation of natural parks and forests, up to the introduction of urban ecosystems. Renewing not only guidelines but also collaboration and exchange of information between nations for the improvement or respect of wooded areas. If necessary, intervening en masse as a community and reforming the national bureaucracy.

Winter City Design: Creating Attractive Public Spaces

Winter is a season where the contrast between indoors and outdoors is most noticeable. During the winter, indoor spaces are warm, cozy, and bright while the outdoor spaces are cold, wet, and dark. Many people don’t want to spend their free time outside. This causes physical inactivity and may lead to some health problems, but there is a solution to this that lies in urban design strategies of winter cities. In this article, we look at some winter urban design and landscape architecture strategies that will help built environment professionals to design more lively, active winter cities.

Design of Winter Cities

These cities are usually cold for most of the year, and health problems such as seasonal depression can occur due to low light exposure and the decline in social and physical activity levels caused by the harsh environment. To compensate for this, it is necessary to focus on creating cozy, bright public spaces with attractive activities. Many cities do not cater well to winter activities, leading to people shutting themselves indoors during the darker months. This is caused by unsuccessful urban design strategies that focus on the use of urban public spaces only in what is perceived as ‘good’ weather conditions. A shift in thinking towards designing for all weather conditions in a 24/7/365 approach can lead to increased public space usage and better physical and mental health outcomes for a wider range of residents.

During the holiday season, when Christmas markets are held, people want to go out to see the attractions and spend time in the markets. These recreational events also affect winter tourism and change the whole vibe of a city during winter. Approximately 85 million visitors frequent Christmas markets in Germany every year. It not only makes a city more lively but also strengthens its economy during cold winter months. We can take these events as an example of a good winter city design strategy. These activities have proven to attract people to leave the comfort of their homes and spend their free time outside. Wintertime markets require not only careful logistical planning but also good spatial planning. A spike in visitor numbers associated with seasonal markets is usually very short-lived. To flatten that curve, and increase the duration of outdoor public space usage, a careful program of activities needs to be created. With this comes the importance of designing flexible, functional public open spaces that can adapt to a changing program.

The correct design of the buildings surrounding public spaces also affects these spaces considerably. Public spaces designed to catch the sunlight as much as possible in the city, prevent wind, and illuminated walkways will make the city feel safe and comfortable while letting it become more enjoyable to be outside in cold and dark winter times. Surrounding buildings also act as natural surveillance, making the space feel safer and more inviting. For a winter city, factors such as snow and ice should be carefully considered. These factors also affect the accessibility of areas, which is one of the most important factors in urban design. Also, shelter systems and canopies can be added to protect crossing points in the city streets. Careful design of routes that offer wind-shielded and rain/snow protected walking and cycling paths encourage residents to navigate the city in comfort. An increase in people visible on the street has a knock-on effect encouraging others to get outside, thus increasing the liveliness of the city streets almost exponentially.

Nordic cities are famous for their winter design. By working with the elements, rather than against them, many Nordic cities create welcoming and comfortable outdoor environments, by encouraging urban skiing for example. This active lifestyle encouraged by activities and events in the winter fosters social interaction to reduce health problems and alleviate stress. Nordic countries are successful in using the opportunities of the winter to their fullest.

Activities for the Winter Cities

The cold weather affecting the city has turned into an opportunity for Nordic cities with various activities throughout the city. They make the existing park features suitable for winter activities such as ice skating, skiing, and tobogganing. Ice skating on ponds and lakes in the Nordic region is a key social activity, bringing people together. Often, these water features are integrated into public parks and designed to be shallow to freeze more quickly, thus extending the skating season.

Another interesting winter activity in the Nordic region is ice swimming – cold days are not an obstacle for this activity. This is something that can also be programmed for in milder climates. Most people in Finland think that it has many physical and mental benefits, and this activity is indispensable for them. Places like Allas Sea Pool and Löyly Sauna in Helsinki are used all year round.

Multifunctional spaces are also key to extending the use of the public realm in winter. For example, running tracks can be illuminated at night to provide ski routes that can be used 24/7. All these features and facilities should be located within walking distance of the city center.
It is very important to support all these with other activities by adding markets and cafes that are located close by, allowing people to stay in these areas longer. The Ice Park in Helsinki located in the Railway Station Square is a key winter-time destination. In addition to skating, there are cafes where people can watch others skate, so they manage to keep people in these areas longer. In this way, social interaction is encouraged and the whole atmosphere of the city changes.

Key take-aways for winning winter city design

  • Flexible and adaptable public open spaces that can accommodate a variety of events
  • A mix of covered and open-air public open spaces
  • Natural surveillance
  • Minimizing wind tunnelling
  • Integrating water features as winter skating parks
  • Creating multifunctional spaces such as running/skiing tracks
  • Use of illumination

Winter cities should be places where people enjoy going out in winter and spending time in outdoor public spaces. Cold weather is not a reason to stay at home; we should adapt our cities to the opportunities created by the cold weather and create welcoming winter environments. Intermittent but regular events throughout the winter and their support with creative lights will attract people to these public spaces. Good winter design can contribute to physical and mental good health throughout the year.

How Urban Degrowth Makes Better Cities

In decades past, urban cities have grown at an accelerating pace while overlooking environmental and social needs to gain wealth. Likewise, the increasing prosperity has led to an increase in overall consumption and therefore immense natural resource extraction. Since the industrial age, cities have been expanding and attracting many residents from the surrounding countryside. Consequently, environmental damages are increasing, but they can be reduced by introducing a contradictory movement– degrowth.

Degrowth has its roots in early 2000s France. It is an ideology opposing the existing model of constant city growth for growth’s sake. And promotes producing only what is needed to sustain the city. Degrowth has the potential to radically transform urban cities towards a more sustainable future with help of subtle landscape and urban design. In this article, we take a look at what architects and landscape architects need to know about degrowth and how to maximize the potential of this emerging phenomenon at a time when cities are seeing an exodus of residents for the first time in a long while.

Do we really need to expand more?

It is widely believed that more urbanization leads to more prosperity. In urban cities, architecture real estate has become the main measure of growth – the grander and more expensive the structures are, the more successful the city is. However, in the process of expanding, urban cities only grow denser. Hence, losing the connection to the natural landscape while putting a strain on its environment. The expansion, therefore, is seen as unfavorable in terms of degrowth. According to its philosophy, modern cities are restrictive and not in balance with nature. Instead of encouraging the overall growth, the degrowth model urges for smart and functional city planning to lay the foundation for the future.

Urban cities need reorganization

To preserve our planet, the degrowth model proposes thoughtful changes to the current cityscape, restructuring and transforming it from densely built concrete jungles to open, natural, and innovative structures. This reorganization is considered essential for a more sustainable social structure, living and work areas, as well as an associated transport system to grant space for the whole community.


The core value of the degrowth city model is a community, in which residents share a common area for living, working, and recreation. Thus, common areas are crucial for the community’s development and success. In contrast, modern cities are planned to be functional and efficient for an individual, therefore often forgetting society’s need for social interactions and also public spaces. Common spaces are also strongly connected to the well-being of residents. Hence, they need to be the main focus for a prosperous future society and the degrowth city. So, the degrowth model proposes to reform the city’s landscape into a more open, natural, and welcoming environment that contributes to community cohesion.

One area which has been shown to work effectively in this philosophy is Christiania, Denmark. Here, residents are in charge of the community, maintaining and developing the area, while also managing the economy, working, and organizing shared activities. With community living, the welfare of people is improved through collective ownership, generous green spaces, and low-density living.

Living areas

The reorganization of cities also requires the reconstruction of living areas. Currently, most cities are compactly built and densely populated, allowing only a little space for naturalistic landscape. This is despite the high demand for open green spaces within residential areas. Increasing natural, communal areas in the degrowth model, would mean a switch to low-density neighborhoods. Thus, the overall city will become more accessible. This is done by introducing urban cities to a degrowth-friendly co-housing model successfully pioneered in Denmark.

The co-housing model includes a common house, shared facilities, meeting and playing areas, and even guest rooms, all free to use, and maintained by the community. By introducing green, communal spaces and facilities to the neighborhood, the area becomes more functional and attractive for the residents, while also being more environmentally friendly. Furthermore, a design strategy of low-impact and high-maintenance will be established. It would recognize structures built quickly and with low construction costs. In the long term, buildings would need more maintenance, but they would also be more cared for and more affordable. Consequently, personal living areas will have only the necessary spaces, letting residents benefit from the public facilities by cooking, gardening, and working together.

Work places

The present work system requires each worker to have a dedicated office space. In contrast, the degrowth work system believes in communal jobs, where residents are employed in community gardens, farmers’ markets, local businesses, and alternative learning spaces, meaning that the most work is done outdoors, in a natural environment. The communal work allows residents to reconnect with natural ecosystems, providing more meaningful and productive performance. As the work in degrowth is moved from indoors – offices, to outdoors – communal spaces, then the city view will change from busy high-rise building blocks to more open low-rise view, where nature plays the main role.


The city transportation system is strongly connected with city planning. With more communal spaces introduced to the cities, the road areas must decrease. This means having more space for people, but less for private transport. Therefore, the degrowth city model prioritizes a branching public transportation system over personal transport networks, while encouraging broad cycling networks and an active “on foot lifestyle”. By reducing the number of roads in urban cities, as has been done in Copenhagen, the private transportation traffic is diminished as residents find alternative transit options to private transport. As a byproduct of reduced private transport, the cityscape becomes quieter, safer, and cleaner, allowing residents to enjoy the communal spaces more.

The future of urban degrowth

We live in times of constant economic growth that is rapidly exhausting our planet. The degrowth model provides a framework to slow down the growth of society and build a new urban city that develops together with nature and the needs of its people. The new degrowth city will be restructured, introducing a community system, new living, and work areas, and diminishing the current high demand for private transport systems. Overall, by reforming urban cities according to the degrowth model, future cities will become more balanced, meaning that nature and man-made structures will play an equal part in the new cityscape.

Are you currently working on any low-density-high public space projects that follow the principles of degrowth? Tell us in the comments.

Increasing Sustainability with Temporary Interventions in the Landscape

As a species, we have the impulse to seek stability and permanence, perhaps because we do not accept the fact that, in the grand scheme of things, we are ephemeral, and this scares us. This impulse is reflected in architecture. Indeed, traditional architecture is always focused on permanence. Perhaps landscape architects have a better appreciation for working in four dimensions, as working with living systems requires an acceptance that nothing is permanent. But what is permanent? We oppose change, but change is the one constant in our lives. Everything is destined to come to an end, so why look for permanent solutions to temporary problems?

In this article, we explore the aspects of temporariness. We look at how it manifests today in architecture and the landscape; we examine the implications of when temporary becomes permanent; and finally, we question how temporary architecture and landscape architecture can be the key to a new way of thinking that increases sustainability in our cities.

Temporary architecture and temporary landscape architecture

A temporary architectural installation is a work designed to last a certain period or to change over time. For example, it can be a single-family home, a piece of micro-architecture, or an art installation. Temporary architectural artifacts are defined by the time they occupy the ground, or when they are adaptable to different uses and users. In the social context, ephemeral architecture could be employed in a variety of scenarios. For example: to accommodate specific events, as a lifestyle choice, as a requirement for a society that reveres change, or as a necessity (emergency architecture). In the field of landscape architecture, temporary landscapes are an increasingly popular project typology. Pop-up parks, Parklets, and temporary art installations have been changing notions of open space. Peter Bishop, Professor in Urban Design at the Bartlett School of Architecture, describes temporary land use as “an intentional phase” where the “time-limited nature of the use is generally explicit”. Currently, the plethora and variety of projects, and the emerging nature of the typology, has impeded society’s wide adoption of temporary landscape interventions.

Many projects are self-initiated, from a ‘bottom-up’ approach, and aim to encourage collective and participatory planning. They use short-term and low-cost interventions to achieve long-term change, in line with the goals of Tactical urbanism. Some cultural associations promote emerging initiatives, such as Camposaz labs, that involve professionals from different disciplines who deal with the design and physical construction of installations in problematic urban areas intending to improve the cityscape.

The problem of abandoned spaces

The traditional way of designing often leads to cases of abandoned buildings and lots. Buildings are often designed for a single function, without due consideration to what will happen once the building reaches the end of its lifecycle. In North America, 2000 shopping malls are reaching the end of their service life. It is predicted that in the next decade some 50% of these will be abandoned. Massive amounts of materials and resources will soon be wasted. We live in a “liquid society” as the famous Polish sociologist Zygmunt Bauman puts it. A society in constant transformation in which everything gets old fast. Commercial spaces open and close in a noticeably short time, in keeping with new market demands.

When the temporary becomes permanent

When temporary structures become permanent, the ephemeral can reflect the zeitgeist. The German pavilion presented at the Barcelona International Exposition in 1929 designed by Ludwig Mies van der Rohe should have been temporary architecture, and yet went on to become one of the symbols of the Modern Movement.

Barcelona Pavilion and Pool by Russ McGinn_CC

Barcelona Pavilion and Pool by Russ McGinn_CC

However, this story is not typical of ephemeral architecture. The Olympic games are an all-too-often sad example of cities investing great resources in structures and installations, only to abandon them later when they cannot be absorbed into the fabric of the city. One example that stands out as a juxtaposition to this trend is the regeneration of the site of the Olympic Park, built for the Olympic games in London in 2012. The park is being transformed into the Queen Elizabeth Olympic Park, which has become fully integrated into the surrounding Stratford and Hackney Wick areas. This transformation brings greater visitor numbers and investment to the borough.

Like a kit of parts, from houses to entire cities

Is it possible to think of a new way of designing and building that includes an assembly kit that can be dismantled? L’Architecture est dans le Pré is the house designed by Claas Architectes, located in the countryside of a small village in France. It was originally conceived as a self-build kit – a dialogue between agricultural construction techniques and economic needs. Temporary architecture can also involve entire cities. A stunning example of this is the ephemeral megacity of seven million people, which is built for a Hindu religious festival, called Kumbh Mela. It is a city that sits on the banks of two rivers. Five materials are used to build this settlement: eight-foot tall bamboo, string or rope, nails or screws, and skin material. It is a method that allows disassembly and ecological reabsorption of all the materials. In a few weeks, this entire city emerges, and at the end of the festival, within a week, the entire city is disassembled. And the terrain is offered back to the river.

How long is too long?

We can define “temporary” as that which is thought to be easily removed, or that can change over time. We can estimate the duration of temporality based on predictable cycles according to functions needed both now and in the future. Furthermore, we can define temporary within the frame of reference of the landscape and how it will transform around the buildings over time.

Temporary and sustainable

It is not enough to use sustainable materials and technologies; we need to start thinking about new approaches and change the traditional way we approach projects. If everything is in continuous transformation, architecture cannot be thought of as static. We should think about cities as living organisms that are transformed over time, adapting to changes in society. We have limited resources, so we need to use them more efficiently. Landscape architects and architects must be ready to continuously reinvent themselves, to think in terms of how installations can be reversible and disassembled at the end of the project’s lifecycle. The key could be to move on from the urbanism of grand visions to the urbanism of grand adjustments. To design for temporary humans and temporary functions, to leave a minimal impact, and to try to extend the expiration date of the planet.

10 Ways to Increase Biodiversity in Any Design

What is the first thing that comes to mind when thinking about biodiverse ecosystems? Probably the hard-paved, concrete, urban environment is not what you have in mind. Though cities are dominated by one species, (which I assume we are both representatives of), they are ecosystems full of opportunities. Urban environments are compositions of prospects and threats. Seizing those opportunities demands from us a new understanding of environmental protection.

Some people might ask why we should care about urban ecology if there is a vast wilderness out there. Yet studies on urban biodiversity show that it is a cause worth fighting for. If you want to know how important urban biodiversity really is, check it out here.

In this article, we summarize 10 methods that will help you create more biodiverse and environment-friendly designs.

Methods for Increasing Biodiversity in Any Design:

1. Protect, restore, mimic

This is the first and most important rule. Get to know local ecology and protect it. If you think there is nothing to protect, look at it again, and look closer. If it is an already degraded area, understand its past and check if you can restore part of what was there before. Drawing inspiration from the past will indicate what plant species to use in your design, and any systems that need renovating, such as daylighting rivers.

2. Use native species

Some may argue that the urban environment is so drastically different, that some native species may not flourish in it; it is always worth investigating. If you aim to increase biodiversity in both the plant and animal kingdoms, native species will support the richest wildlife. And always remember to avoid invasive species or any that may become invasive in your design area.

3. Create layers

This method is only applicable in climates where layers are the natural order of growing. Although traditional lawns are one of the most popular landcover approaches, they do not provide much of a habitat for wildlife. More naturalistic planting, like flower meadows, can support butterflies, and bees. Taller tussocky grass may become home to animals that are not satisfied with turfgrass. This meta-analysis study from Germany has demonstrated that biotic factors, like vegetation structure, are extremely significant in supporting wildlife. Here you can check other arguments on whether to banish lawns or not.

4. Diversify

Ph. D Sofie Pelsmakers in her book ”The environmental design pocketbook” suggests, that to avoid disease, pests, and to support biodiversity, you should select plants from a maximum of 30% of the same family, 10% of the same genus, and 20% of the same species. If you design a larger area, you should also follow the suggestion of Tan Puay Yok from the book “Nature, Place & People: Forging Connections Through Neighbourhood Landscape Design”, to diversify types of ecosystems.

5. Do not gild the lily

Every space in the design area should be carefully thought through. However, sometimes it might be advantageous to leave a fragment for Mother Nature to design. Natural succession and preservation of natural vegetation are the most failsafe ways to incorporate all the methods outlined above to increase biodiversity.

6. Offer food, shelter, and nesting place

We may have an influence over-designed vegetation, yet controlling other kingdoms such as invertebrates, mammals, and birds, is not so easy. Nevertheless, providing food, shelter and nesting places might be our best shot. Always support existing habitats with a respectful approach. Different species might need different methods. For example, a high green roof may attract butterflies but be inadequate for bees. House sparrows appreciate nesting 2m above the ground, while peregrine falcons need nesting sites to be more than 20m high, preferably with a good view for pigeon-pray.

7. Minimise light and noise pollution

Those two can cause psychological stress in humans, as well as in other animals. Nobody likes to live in a hectic area. Therefore, to not repel biodiverse wildlife, keep light away from their resting spots, like ponds, tall trees, and hedges. According to Ph. D Sofie Pelsmakers, light below 3lux at the ground, ideally 1 lux, is required. Avoid white and blue wavelengths.

8. Build corridors

If you followed all the previous tips, you have now quite a decent potential habitat! Now is the moment to allow animals to get to it. According to the previously mentioned meta-analysis study connectivity is one of the most significant factors influencing biodiversity. Connectivity in the matrix is crucial because otherwise, you risk fragmentation and the creation of an ‘ecological sink’ for animals to die in, without enough genetic diversity to sustain subsequent generations.

If a true corridor is not possible, try steppingstones. They might not be as successful as corridors, but they may be a good compromise of cost and ecology. A nice idea for this approach might be pocket parks.

9. Reduce threats

Assuming you already considered providing shelters, another aim could be to reduce bird mortality. Birds often fly directly into the  glass as they confuse reflections with reality or try to fly through the building. A lot of them die. If you want to avoid this pointless animal death, you can avoid planting new trees near the large glass surfaces and corner windows. Probably the best approach would be to not use big surfaces at all in the first 23m from the ground or use glass safe for birds. You can find other guidelines and information here.

10. Consider management

According to a recent international report, there are four management activities that you should avoid. The report reinforces the point made in method No. 3 above, that short turfgrass lawns and the simplification of habitat structure can have detrimental effects on biodiversity. Another interesting example is not being too tidy. One Australian example from 2010, demonstrated that just leaving leaf litter increased bird species richness by more than 30%. Hedgehogs and other small animals would also appreciate this technique. Lastly, it is important to consider pesticide and herbicide applications, as they usually cannot recognize “good living beings” from “bad living beings” and indiscriminately kill. By design, they reduce species-richness of plants, therefore repel animals.

Time to act on biodiversity in design

Biodiversity is reducing across the planet. It is neither the time nor the place to ignore biodiversity in our designs. Taking species diversity into account might look challenging, but even these simple methods outlined above will help. Firstly, respect what is there. Then consider diverse, native planting, that will attract animals. Then make your designed habitats as hospitable as possible with prescriptive maintenance.

Is Biodiversity in Cities Important?

We all know biodiversity is important. Much has been written about it in both scientific literature and public media. But how important is it? What role does biodiversity have to play in our cities?

To answer those questions, we must differentiate the arguments for environmental protection. Differing arguments result in different approaches. For example, depending on if you want to protect local ecology, provide ecosystem services, or climate-proof an ecosystem, you may choose to use only native plants or also add those from outside of your region.

According to research by Ph.D. D.C. Dearborn and Professor S. Kark, there are 7 main motivations for conserving urban biodiversity. In this article, we examine the most important motivations for protecting and increasing biodiversity in cities.

Preserving local species and ecology

Cities have historically flourished in areas of high productivity, such as seashores, riverbanks, and deltas. Areas that were usually characterized by their high diversity in animals and plants. According to research on urban biodiversity from Arizona, it may be an effect of the rich geology in these areas. Over time, we have eroded these ecosystems, leaving behind only what was useful to us, with disregard for the indigenous wildlife that relied on these ecosystems. We may never be able to restore what was lost in those areas. However, we may be able to create safe havens that can accommodate local species.

Creating steppingstones to non-urban habitat

Connectivity in active ecosystems is key to sustaining any population. Even if animals will not feed or breed in the urban area, they may need to pass through it. Stripping them of this possibility might destroy not only the ecosystem in the city but also the surrounding, interlinked ecosystems, by creating fragmentation and ecological sinks. The population will either quickly become locally extinct from the lack of resources or will be able to survive there only a few generations, lacking enough genetic diversity to survive long term.

Understanding and facilitating responses to environmental change

The long-term goal of preserving a biodiverse planet is to allow lifeforms to build climate resilience. Species-rich ecosystems are more likely to adapt safely to the changes happening around them. Moreover, the research from Israel previously mentioned suggests that green areas in the urban matrix can help ease the transition of species to accommodate these new, man-made environments. As observers, we can survey this amazing process and document it, expanding our knowledge about evolution.

Conducting environmental education

Environmental protection does not need a few active individuals as much as it needs considerable numbers of people playing their part. Yet people are spending less and less time outdoors. With this lack of connection with nature comes a decrease in environmental empathy. Access to nature can be increased by designers providing naturalistic environments closer to home in the urban environment.

One great example of environmental intervention and education might be the story of Austin, Texas (U.S.A.), where the renovation of the Congress Avenue Bridge led to its colonization by free-tailed bats. Before then, the colony was banished from one place to another. Now, the renovation and subsequent environmental education resulted in a bat-paradise and an annual gathering of thousands of people, who come to see the flying spectacle adding to the local economy through eco-tourism.

Providing ecosystem services

What is a more effective area to place human-helping services, than where the density of population is highest? In cities even small, but well-planned designs like pocket parks can improve the way of living. Greenery can ease the urban heat-island effect, suppress noises, improve urban hydrology, and more. The Urban wetland in London created in the area of a former drinking water company eventually became an important biodiversity point on the map of London.

Fulfilling ethical responsibilities

If your aim is fulfilling the moral obligation we may have as humans, the first thing should be to talk with local people, as every culture differs in what matters to them. Community environmental action can have a positive effect on a community and a sense of belonging.

Improving human well-being

Proximity to green environments is well known to have positive effects on physical and mental health. Research by PhD. Roger S Ulrich from the Chalmers University of Technology proved that even as little as looking outside the window on green spaces may lead to a quicker recovery. Moreover, ecosystem services, like the reduction of air pollution, add significant value to the quality of life in cities.

Preventing urban sprawl

Although this point is not mentioned by researchers D.C. Dearborn and S. Kark, the European Environmental Agency (EEA), in their report “10 messages for 2020”  noted, that making life in the city more connected to nature, thus more attractive, may prevent urban sprawl and therefore save space for wilder areas outside the city.

The importance of urban biodiversity

If at least one of those arguments got to your heart, we may agree that taking care of urban biodiversity should be our priority. Although it may not be so glamorous as wild seashores, plains, and mountains, its proximity to a dense population makes it more effective in solving some more immediate local challenges. Therefore, it doesn’t matter if your priority is fulfilling our responsibilities towards the environment, or improving the quality of living, increasing biodiversity in our designs is a good way to achieve many goals.

How to Avoid Social Segregation in Play Spaces

Built environment professionals have an opportunity to influence not only the physical environment but also the societies that use the spaces we create. Much has been written in recent popular media regarding social segregation of play spaces in developments. Developers have been accused of creating play spaces that exclude certain portions of residents in their designs. In this article, we look at what landscape architects and architects can do to increase social integration through play provision.

Social segregation in the past

Arguably, segregation has been a significant problem for a long time. Who can forget the appalling racial segregation in South Africa under apartheid that lead to whole urban areas being declared off-limits to black South Africans? While such stark examples may be unthinkable to the majority of people today, the rise of gated communities in North America and council estates in the UK has accentuated and perpetuated an age-old trend for social segregation that probably even predates the castle keep and peasant villages of the days of yore.

Current trends in social segregation

Many planning restrictions and building codes require developments to have a certain amount of affordable or social housing within a development. The idea is that people from under-resourced backgrounds should have access to well-designed accommodation in the same area as people from more wealthy backgrounds. However, developers usually receive a greater return on more exclusive owner-occupied units. This places commercial pressures on developers to maximize higher-cost housing, often at the expense of social housing. This has been highlighted in recent years through the ‘poor door’ scandal, where residents of social housing are provided with a separate door. The fundamental aspect is the social segregation of what’s perceived as two types of people – the “haves” and the “have nots”. This is exemplified in the idea that privately-owned housing is literally made more exclusive by excluding the social tenants from the main door. The Altitude scheme in London drew particular criticism for placing the entrance to the affordable housing down a back ally primarily used for garbage collection.

Segregation of play

The problem of social segregation goes beyond dividing entrances. For example, in London, several schemes have come under fire for making different provision of outside spaces for privately-owned residences and social housing. The Baylis Old School mixed residential development in South London boasts 149 homes featuring “huge windows looking out over the lovely gardens”. The Guardian reported that the developers marketed the scheme as having “common areas” that are “there for the use of all the residents”. However, after planning permission had been granted the plans were altered to block social tenants’ access to some communal areas. Henley Homes, the developer, has countered that the development has subsequently been split in two with different management companies looking after the owner-occupied and social housing areas, resulting in different play provisions for each area. This case is not unique. Many examples from across London have been revealed where social tenants and mixed ownership apartments do not have access to play areas and facilities.

The effects of segregated play

Criticism of segregated play areas comes from both sides of the divide. While families in social/affordable housing lament the poor provision for play, residents of owner-occupied housing regret that their children are not able to play with their school friends in the same play spaces within the development.

Social segregation has well-documented impacts on health and longer-term inequality. By segregating facilities at such an early age, children are made aware of the inequalities in society. Growing up in these conditions helps perpetuate that inequality.

Dividing provision for residents based on income inequality also impacts upon other discriminatory areas such as race. People who identify as coming from a visible minority background statistically have lower incomes. Therefore, segregating play provision between income backgrounds can have knock-on effects for social and cultural integration. More diverse neighborhoods have greater tolerance. Allowing children of all backgrounds to play together stimulates greater tolerance for the next generation.

The solution to socially inclusive play spaces

Many architects and landscape architects already appreciate the intrinsic benefits of inclusive spaces and design for the needs of all residents. Policymakers also often understand these issues. However, developers argue that the inclusion of social housing has negative impacts on the profitability of market housing. In cases such as The Baylis Old School, plans are altered after planning permission has been granted. One solution might be to better legislate the equal and inclusive provision of play spaces for all residents and then following up post-planning to ensure these measures are implemented. Another approach might be to insist that all developments include social housing and inclusive provision for all children. This might create a level playing field that removes the competition from exclusive developments that puts commercial pressure on developers to compete with these developments.

As built environment professionals, we can adopt best practice design solutions that foster social inclusion and insist that they are utilized in our projects. Well-designed paces might include:
• Communal play spaces that are designed for both owner-occupied and social/rented accommodation
• Locating communal play spaces centrally to avoid implied ownership
• Designing out barriers between different areas
• Locating access points equally between all types of housing within schemes
• Incorporating diverse play equipment and providing open spaces for interactive and team sports/play
• Participatory design – hosting consultation and design events amongst all stakeholders and facilitating discussion
• Precise yet inclusive rules for engagement, use and maintenance
• A program of events to create interest in the play are and foster social cohesion

We should also adopt a firmer stance with clients and developers who might request changes to plans that have already obtained planning approval or building permits. It may also be appropriate to inform local planning authorities where schemes have departed from the consented plans.

Avoiding social segregation in play spaces

As landscape architects and architects, we have a duty not only to our clients but also to society. We are aware that we should be designing inclusive spaces, but there are often pressures from developers to design separate areas for owner-occupied and social/rented housing or to alter drawings post-planning to place boundaries in areas cutting off access to play areas. There needs to be a change in the planning process and better provision for post-planning follow-ups to ensure what has been granted permission or issued permit is actually built. However, we also need to ensure we adopt best practices for designing inclusive play areas within housing developments.

How to Avoid the Pitfalls of Gentrification

Gentrification is a term that emerged in the mid-1960s to explain the demographic and social changes that some neighborhoods in the London were experiencing. Since then, a vast number of articles and essays on urban transformation have sought to explain this phenomenon.

In this article, we shall explore how to detect areas that are likely to be affected by this process, how to identify those that are already being affected and how to prevent this from happening to preserve heterogeneity, social inclusion, and sustainability in our cities.

But what exactly is gentrification?

The word gentrification coming from the English syllable “gentry”, refers to the British rural nobility. Gentrification was originally coined to describe the emergence of middle-to-higher-income social groups in neighborhoods that led to the displacement of the working classes that originally inhabited these areas. This resulted in a loss of local identity and fragmentation of the community. However, gentrification is no longer restricted to urban centers or first-world metropolises. As Jason Hackworth and Neil Smith wrote in their essay titled ‘The Changing State of Gentrification’: “Gentrification is the leading edge of the urbanization of human evolution‘.

Leyton High Road, in Waltham Forest, London. was given a makeover before the 2012 London Olympics.

The globalization of gentrification.

The Polish sociologist Zygmunt Bauman coined with the term “Liquid Modernity” which refers to a phenomenon that leads to the creation of egalitarian consumption patterns, a loss of cultural diversity, and an uprooting of identity. In this paradigm of a lack of personal commitment to long-term local goals, there is a contradiction between the search for freedom, the desire for change and the fear of not knowing what will happen.

The ephemerality of current values that were highlighted the global economic crisis in 2007 and the ongoing environmental and migration crisis can be understood to be a particularly western perspective problem. Historic values and traditions are undermined, generating a false identity that temporarily binds these communities but is built on weak foundations, causing uprooting of populations.

Carnaby Street, London, 1982 and present day

Carnaby Street, London, 1982 and present day

As we can see in this image, the traditional local shops in London’s Carnaby Street have been replaced by international corporate companies resulting in a neighborhood that lacks a strong local identity and affordability.
Fortunately, the notion of ‘use and throw away’ that consumerism has given us is changing into new movements. A responsible action considering the global trend towards urbanization and the effects of climate change with proposals such as promoting the circular economy can add value and improve the sustainability of the neighborhood. Thus, globalization is one key precipitator of gentrification.

Tips for identifying areas susceptible to gentrification.

  1. Dwellings are usually small, and the rent prices are low.
  2. The profile of the inhabitants is low income, usually without higher education.
  3. Urban decay. Existence of a general degradation of the neighborhood and it’s infrastructure.
  4. Proximity to other areas with higher rental values.

Although each area has its unique circumstances, these broad factors can mark the potential for financial speculation that drives property prices, pushing out existing populations through increases in rent, inflated offers for their properties, or as a result of the rise of the cost of living. This marks a phase of expulsion, investment, and marketing.

The demand for more green spaces by the inhabitants of Chicago sparked the idea of reusing an abandoned railroad line as a linear park. The 606 (named after the Chicago ZIP Code prefix), was opened in 2015, with community support and consultation forming part of the design process. They wanted a path for people who lived there. Given the recent economic crisis, no one expected home prices to rise. However, the investment in the area leads to increased interest from investors and higher earners, leading to a degree of gentrification. But important lessons were learned, and steps have been taken to mitigate this, including a recent push for affordable housing in the area. The experience gained is being applied to other parks projects in Chicago.

Tips for detecting gentrification as an ongoing process.

  1. Galleries and small arts and crafts shops appear. Artists are often the first to arrive attracted by historic architecture and low prices.
  2. Plans to improve public transport and connectivity.
  3. Real estate demand increases sharply.
  4. The number of international retail outlets increases.
  5. Gradually, the social shape of the neighborhood changes to a demographic of higher earners.
  6. Investment of green areas, public spaces, and road lighting.
  7. Crime rates fall.
  8. Tourism increases. Entire buildings are converted into holiday rental apartments.

Tips for avoiding gentrification.

It is important to be aware and consider the responsibility that comes with urban intervention and its social impact. Every urban planning project must involve the local community and contemplate the area in relation to its context, seeking a socio-economic balance in a sensible and measured way and never as economic policy.

Practical steps that can be undertaken to minimize gentrification:

  1. Detect the situation in time. What’s going on? Who needs to be involved? Which is the most vulnerable population? Talk to neighbors and stakeholders.
  2. Turn problems into goals. Establish a list of neighborhood issues and possible solutions in conjunction with the local community.
  3. Develop an action plan. Consider the resources available. Involve the community and consider their skills. Integrate these into existing policies, plans, and programs.
  4. Measure the results of these interventions including quality of life.

The Mission neighborhood in San Francisco has always been a neighborhood of immigrants and minorities. In the 1980s it became a hub for the LGBTQ+ community, being a marginal but inclusive area. Now, because of a range of factors including, a rise in population and the attractive (and relatively affordable) Victorian houses in the neighborhood, there has been an expulsion of current residents due to the increasing rental prices.

However, residents are still struggling with art, community, and activism to preserve the cultural environment of the minorities who reside there, seeking social justice, and resisting the financial interests north of Market Street. They have been able to take advantage of their problems with activities such as the creation of tours where local artists explain the history of the neighborhood in murals. The quality of the streets has improved, and citizen security is ensured by social control.

It is important to keep in mind that it is not about looking to blame social groups that move in because of their economic advantage or deride artists who open shops attracted by low rents. What is troubling is the distribution of land ownership, land speculation, and the vulnerability of the population exploited in favor of financial gains. The rest are consequences. As designers, we are committed to creating spaces that solve the needs of their end-users, with the greatest possible satisfaction and the best possible user experience.

Can landscape architecture and urban design solve the problems of gentrification

Careful planning of green spaces in consultation with the community, for example, can avoid a pocket park from becoming an attractor for gentrification, while adding positive effects to the health and well-being of the existing local residents.

While urban design and landscape architecture may not be able to entirely solve the problem of gentrification, as designers of cities, we can make sure that our projects do not compound the issues of disenfranchisement of minority and vulnerable communities, loss of local identity, and increased land speculation that can lead to gentrification.

How Public Open Space Reactivates the City

Public open spaces are vital for understanding cities. They are the main environments for citizens’ interaction and stimulation. While cities create the physical environment for social life, public spaces work as the stage and catalyst of social interaction. Therefore, well-functioning public spaces are crucial for any urban environment due to being physical spaces for civic participation, sense of belonging, and social integration. Likewise, a lack of common space results in the decay of the social structure of the city by limiting possibilities for simple communication and interaction. However, urban public space tends to be more and more exclusive due to top-down planning and standardized practices with limited adaptability. This is further compounded by market forces leading to the privatization and commercialization of public spaces.

A Crisis of Planning

The journalist, author and activist Jane Jacobs refers to the “crisis of planning” as top-down planning tools which don’t give enough flexibility to urban and social changes. With these practices based on functionality and efficiency, cities began to be more exclusive and interactions between people have started to loosen. Therefore, this situation not only results in unused and unpleasant urban environments but also diminishing social interaction.

If we compare mediaeval cities with modern cities, we gain insight into the decisions we make which create more and more exclusivity in our cities. Mediaeval cities were a product of a continuous process almost devoid of intentional design, allowing spontaneity with no division between different functions. Modern cities, however, are often based on functionalist concerns which aim to solve problems with land-use practices, without considering social impacts. While the mediaeval city gives opportunities for social interaction; the modern city tends to segregate the different user groups in different areas of the city. In this case, the existence of designed public spaces does not become an opportunity for social interaction between different social groups as it does not create any commonality of daily activities targeting the different groups. The famous example of the Brasilia Plan designed by Lucio Costa draws a significant picture of how the basis of modern architecture and land-use practices failed to create a dynamic city structure while aiming to create a well-functioning ideal living environment.

Public Spaces as Stitches

To maintain a healthy and well-functioning urban environment responding to residents’ social and physical needs, the existence of public spaces is crucial. Architectural and planning decisions can contribute to the social and cultural patterns of the city by limiting certain activities while creating opportunities for others. Therefore, an urban environment which is suffering from the drawbacks of the planning practices mentioned above can be reactivated through specific interventions of well-considered public spaces by stimulating interaction between residents and inclusion in the city pattern. However, several key factors can contribute to the viability of public spaces in the long term; maximizing the usability of an area to achieve the ideal of a “city for all”.

Continuity and Hierarchy of Public Open Spaces

To enhance the positive outcomes of public spaces and sustain usability through maximizing integration, it is crucial to consider them as parts of a continuous matrix. The importance of different types of well-functioning public spaces in different scales is a key factor of an open, inclusive city.

For instance, pocket parks have greater effects on residents and commuters at the neighbourhood scale, due to their relative easy implementation and proximity to living environments. Bigger recreation and sports parks contribute to public life at the district scale. Also, the continuity between different public spaces affects the viability of each space individually and the quality of the living environment across the whole city. This situation derives from the fact that each small scale intervention is a product of a greater planning strategy that forms the dialogue between residents and the decisions being made about their environment. Also, when the actual physical environment is considered, the continuity of public spaces affects the experience, the interaction between residents, and the walkability in the city etc.


When designing inclusive spaces, the idea of diversity becomes crucial since integration relies on the existence of different activities and social classes together. The most important factor is the coexisting of varying urban functions and different types of built environments contributing to the usability of the public space by maximizing the possibility of interactions, synergies, and stimulations between different functions and user groups. Integration comes from the diversity of the events and activities that the public space is providing a platform for.

A contemporary example of diversity can be seen in Superkilen in Copenhagen which shows how the diversity in physical space can encourage different activities, resulting in people from different backgrounds coming together.

Adaptability and Flexibility of Public Space

Since the social, economic and cultural patterns and needs of a city are not static entities, the public spaces which host these values should be adaptable to the changes in social life. When public spaces are rigidly designed as areas on which every activity is meticulously planned, public spaces become insufficient when new needs arise. Therefore, either they become vacant areas in the city or they are demolished to make room for something else as new demands become apparent. In other words, public spaces must provide opportunities for the activities created by residents and ensure spaces are capable of adjusting to different needs. The project of DeUrbanisten is a great example of how public space can be designed to be flexible and effective in minimizing the risk of becoming redundant.

Public Participation in Urban Design

When it comes to the viability of public space, it is very important to have a bottom-up approach to allow people to become active participants in the development of the space, rather than being passive users. When the community is involved in the process of decision making, their engagement with the public space becomes much higher. Also, it maximizes opportunities for identifying particular problems regarding residents’ needs. While doing this, it creates opportunities for interaction between residents by creating a common ground. The well-known example of the High Line shows the opportunities created with a bottom-up approach and the success of public participation in the effectiveness of the project.

The Value of Good Public Open Space

It is undeniable that public spaces contribute immensely to creating healthy, well-functioning urban environments. Landscape architects have a great responsibility to create socially sustainable places. By adopting a bottom-up approach and keeping inclusivity in mind, it is possible to ‘re-stitch’ fragmented urban environments by creating platforms for diverse social interactions.

How Circular Economy Can Build Sustainability

The circular economy seeks to move beyond traditional manufacture, use, and dispose culture to build resilience into systems, products and services throughout their lifecycle and beyond. In this article, we look at the circular economy and how it can be used in urban design and landscape architecture to improve sustainability.

Linear Economy

Our current approach to consumption is largely a linear process. We purchase products, use them for their useful lifecycle, and then discard them. Often this waste is not recycled or reused and simply ends up in landfill.

In nature, very little is wasted. Often the faeces of one organism goes on to feed another, which in turn creates waste products that add humus to the soil. The nutrients from the humus ultimately fertilize vegetation in a closed loop that is self-sustaining.

Watch: Re-thinking Progress: The Circular Economy

Circular cities

Our cities can be a major source of circular systems. The global population is expected to reach 9.8 Billion by 2050; some 66% of whom will be living in urban areas. That represents around 6.5 billion consumers living in the cities we create. As designers of the urban fabric, we are uniquely placed to influence the future of consumption in cities.

The goal of using circular economy in urban design is to create systems and products that not only reduce consumption while reducing waste but also create economic and social benefits.

Including circular economy principles in urban design requires collaboration between public and private sectors in a non-competitive approach.

Closing the loop

Implementing circular economy into projects can be undertaken at all scales. Firms like Circular Landscapes are using the circular economy to create projects that bring economic, social, and environmental benefits to their neighbourhoods and beyond. From more strategic level cases such as Climate-active Cities that outlines climate strategies for various types of cities, to projects like Springfields that looks to make agricultural irrigation more sustainable and circular; Circular Landscape’s projects illustrate the power of the circular economy thinking at the project level.

Making the linear, circular

There are several ways in which built environment professionals can add value to the circular economy and improve the sustainability of the projects we work on. In Hiedanranta, a new 25,000 inhabitant urban district in Tampere, Finland, Jolma Architects is working with a team of international architects, landscape architects, and transport specialists to implement circular economy thinking at the structure plan and master plan levels. For example, we are preparing for a reduction in private vehicle ownership in the future by specifying parking buildings that can easily be adapted for other uses as demand for car parking spaces reduces. These parking buildings also act as material collection points that encourage people to recycle their waste by making it as easy as possible. Waste organic material is used as fertilizer for local food production with low food millage. A heavy focus on renewable energy ensures that the infrastructure of clean energy production is implemented from the start and is easily adaptable for the future.

One specific example of waste to energy in Hiedanranta is the Tampere University of Technology’s trial of urine to create power. Urine is collected and processed to provide nutrients with which to grow algae that is then used as biomass fuel in energy production.

Linking the chain

By specifying recycled and reused materials throughout the supply chain, we can reduce waste and energy consumption, and often save money in the process.  Gamle Mursten is a company that upcycle materials by collecting used bricks, clean them using vibration techniques, and sell them on. Thus, ensuring a waste product of the demolition industry is reused for future generations. Similarly, the Danish company RGS90 recycles waste porcelain products and insulation into reusable and recyclable building insulation such as ROCKWOOL.

Levels of circular economy in the city

Another project we are involved in investigates how sustainable circular economy principles can be applied practically in an architectural project. Together with Evolving Symbiotic Cities (ESC), Jolma Architects is working on the circular economy project, Circular City Blocks, in the North Bank area of Hiedanranta. The project is the brainchild of Cireco. “Cireco works with partners to create… efficient and high-quality projects that are based on producing zero emissions, clean materials, and resource-conserving design in accordance with the principles of circular economy.

Several options for North Bank have been investigated, from a single circular economy tower to a sustainable street, and even a whole circular economy city block. The project utilizes principles such as:

  • Built for disassembly
  • Modular construction
  • Adaptable and flexible spaces
  • Integrated and shared services
  • Resource efficiency
  • Vacuum-based sewerage system
  • Renewable energy and storage
  • Combined heating and cooling systems

North Bank Hiedanranta was presented at the World Circular Economy Forum 2019 by Cireco in Helsinki in June.

Landscape Process as Circular Economy

Landscape processes can also add value to the circular economy. In traditional water management, wastewater is treated and then discharged into watercourses. This water is not always adequately processed. A 2017 United Nations report states that globally an estimated 80% of wastewater is discharged into watercourses without adequate treatment.

Constructed wetlands offer opportunities to harvest wastewater and clean it by means of phytoremediation. This creates an economic benefit in providing a product (cleaner water) as well as environmental benefits through habitat creation and social benefits in amenity space.

Much has been written about the ecosystem services of urban forests; from mitigating the urban heat island effect, stormwater management, and managing the pollution cycle. Urban forests can provide locally sourced products and amenity space while providing these ecosystem services.

Circular Thinking

By changing our thinking from a linear economic modal to a circular one, built environment professionals can facilitate connecting waste products and processes in the city. Circular economy results in local economic, social and environmental benefits. Whether it’s designing better, more circular, neighbourhoods, incorporating circular technology and processes into our projects, or influencing the supply chain to bend an existing linear economy to make it circular, we are uniquely placed to make substantial long-term impacts upon our cities. We would love to hear how you are using the circular economy in your work. Please share some examples in the comments section below.

Tampere: The Most Exciting City You’ve Never Heard Of

Tampere (Finland’s second city) is the largest inland city in the Nordic region, serving an area containing over 505,000 inhabitants. With a long and productive industrial heritage, Tampere is the fastest growing city region in Finland with a projected increase in population of 23% by 2030. With this rapid expansion and internationalisation comes a staggering estimated €6 – €10 billion investment in the city. In this article, we take a brief look at how some of that €6-10 billion is being invested in the urban design of this prosperous city.


One of the major investments currently being implemented in Tampere is the new 14-mile (23 km) tramway, which connects the city centre with Hervanta to the south, the university hospital to the east, and in the second phase Hiedanranta and Lentävänniemi to the west. This smooth and seamless transit network connects with local buses and cycle routes to provide sustainable public transport options. Each tram will carry 240 passengers or the equivalent of three buses or 185 cars. The first phase of the tramway will be completed in 2021, with the second phase due to be completed in 2024. The design and construction of the tramway will be undertaken by Tramway Alliance made up of the City of Tampere, Tampere Tramway Ltd, YIT Construction Services, NRC Group, and Pöyry Finland Oy.

In addition to the benefits to public transit, the tram project will include upgrades and benefits to the public realm. For example, many new green areas are planned along the route of the tram, including the planting of over 200 trees. The main street in Tampere, Hämeenkatu, will also receive upgrades in the hard landscape materials and street lighting.

Travel and Service Centre

The new tramway will feed a central transport and service hub in Tampere, where all modes of transportation will come together. The international ideas competition to design this centre was won by Danish architects COBE and Finnish architects Lundén Architecture with their proposal ‘ReConnecting Tampere’. Detailed plans for the transport hub are due to be completed in 2019, with the first phase of construction already underway. Cobe and Lundén Architecture’s vision for the area includes a new Central Park which will act as a green lung for the city. The recreational landscape will provide year-round activities for local residents and visitors and will include a vibrant commercial arcade, acting as a link between the upper deck area and the lower level park.

Central Deck and Arena

Above the railway tracks, there will be a new downtown centre accommodating a world-class ice hockey and entertainment venue with a capacity of 13,000 people. The area will also house a 21,500 square foot (2000 m2) casino, and some 1,000 new apartments. The Deck area has been master planned by Studio Libeskind, together with project architects  AIHIO Arkkitehdit oy, structural engineers Ramboll Finland, and zoning by WSP Finland Oy, with SRV as the main contractor responsible for design, development and construction.

Hiedanranta is a new district to the west of Tampere that, when complete, will accommodate 25,000 inhabitants and create around 10,000 new jobs. In 2017, the international ideas competition was jointly won by two proposals: Innovaatiolahti by Mandaworks of Stockholm, and Schauman & Nordgren Architects of Copenhagen; and the Reflecting TRE proposal by Arkkitehtuurityöhuone BUENAVENTURA (Later Jolma Architects, TUPA Architecture and Architecture Studio NOAN) of Tampere, Finland. The structure plan for the district was adopted in December 2017, and the master plan will be completed soon. The adopted structure plan features a new downtown city centre built around a historic refurbished and repurposed factory and three large islands on the lake. Hiedanranta will be connected to the city centre via the new proposed tramway. Green and blue infrastructure networks wind throughout the proposed development connecting places and offering passive and active recreation opportunities. A large central green corridor integrates the existing city block structures of two areas and accommodates new recreational parks and green spaces, acting as a large central park for the district.

Hervanta is an existing district located to the south of Tampere comprising a mix of 1960s and 70s architecture and university campus. In 2017, BST Arkkitehdit Oy, together with Sito, Hartela, and artist Karoliina Suonio won first place in the ideas competition to design new blocks for the northern axis of Hervanta, including 930,000 square feet (86,400 m2) of residential space, and 368,000 square feet (34,200 m2) of business and commercial space. The proposal integrates the new tram line, while providing green roofs, and active ground level functions organised around public open spaces.

Vuores is a new sustainable district located to the south of Tampere surrounded by unspoiled nature. The area is already under construction, featuring a downtown area arranged around the Vuoresakio central square, and several suburban neighbourhoods. Once such neighbourhood, Isokuusi, will become a beacon of sustainable industrial wood construction, and incorporate renewable energy and smart solutions. The master planning has been undertaken by B&M Architects. The area will eventually form the largest wood-constructed area in Finland. Single-family homes and multi-storey apartment buildings will be built from new, innovative, and sustainable wood products.

Access to nature and green spaces is a key feature of the Vuores master plan. The central park in Vuores acts as an outdoor living room for residents to meet and relax. The park will also perform ecosystem services through stormwater management with stormwater basins, water routes and flood meadows. Several allotment gardens are planned and will include accessible raised-bed style planters, ensuring all residents have the opportunity to grow their own sustainable food.

Future Cities

The secured investment of €6-€10 billion in Tampere represents an ambitious plan by the City of Tampere and its partners to reinvigorate the city’s urban fabric. The strategic planning of the city as a whole enables new areas to be connected via the new tramway that will stimulate urban redevelopment in existing areas. Proposed developments like the Central Deck, with its casino, hotel, and multi-purpose venue will attract visitors and businesses alike. New mixed-use and residential areas such as Hiedanranta, Hervanta, and Vuores will ensure the sustainable growth of the city in the future. Sustained growth of cities is difficult to achieve. However, by carefully planning ahead, integrating phased development, sustainable public transit, and taking advantage of ecosystem services provided by green and blue infrastructure, Tampere is set to become one of the most attractive cities to live and work in the Nordic region.
