Frank Lloyd Wright Usonian home for sale
I know that at 2,6xx square feet it's a bit large for our standards. But the whole renewed focus on the "not so big house" really is embodied in Wright's Usonian designs. This one is even more special because it was designed to be 100% wheelchair accessible. In 1948. So, there you go! Universal compact design, old-school style!
