This forum contains a lot of do-it-yourself projects, which this definitely is not. That said, I think the integrated passive solar, air flow, grey water and other techniques in this urban community design are fascinating. And I am always looking for ways that lowering our impact can go more mainstream.

This is a Seattle-area architect who is on the cutting edge of making livable, dense-in-a-smart-way, affordable (um, in a mainstream sense any way), community-oriented housing, albeit of course using more standard materials and methods.
So, for those of you doing/desiring urban permaculture, would you live in a place like this? Of course, the design still has the plantings in
rows, and such, but that could be fixed.
