There is a lot of talk about mixed use and redevelopment. Most of what I see are new projects which attempt to (re)make a "city center" or "walkable district" although you have to drive out to it. These developments are either greenfield development or development which start on vacant land. None seem to adapt existing residential structures.
Does anyone know of any examples of areas which were residential which are now mixed use? Particularly, I am looking at a neighborhood of predominantly multi-story buildings (generally 2 to 3 story) with one residnetial unit per floor. There is no commerial. Has anyone seen a move to vertically integrate uses in existing residential structures?
Is this feasable given the costs of converting the residential space to commercial space (anything other than a small office)? Thoughts?
