Looks like another great way to start programming multiple levels of space and functionality into urban environments. The food connection adds to the opportunities for community building, education, and access to a more wholistic landscape, + fresh vegi’s do taste better when just picked.
I am curious why the idea has to stop at the buildings edge though? Extending the idea outward could start to mitigate the effects of the large parking lots surrounding grocery and other big box stores by reducing stormwater runoff, reducing the heating effect of exposed paving, while adding interest and complexity to the landscape. Such a structure could also provide shelter for people entering the store during inclement weather and reduce the need for snow plowing in northern cities.
An idea full of possibilities!
