I operated a design/build company for 25 years where most of the work we did in-house with some sub-contracting on the specialized features. I now work by myself designing and then managing the projects. I have a network of contractors that work on these projects. I have a design fee and then negotiate a management fee with the homeowner/client. The contractors have their own contracts directly with the client. It is a clean, up-front model that has worked well for me. Of course what I do now was a transition from the design/build model which had a well-established customer base. Referrals have been and currently are the source of all my work. I loved the hands-on approach working with the crews, but what I do now still allows me involvement in the construction process and this helps insure intergrity from design to completion.
