I'm curious what, specifically, the foundation claims is contrary to the plans. It's not like Wright himself built the houses (or did the drawings, for that matter). There's always been a process of modification when the contractor gets onsite and builds something. When Wright was alive he (or his secretary) would review pictures of the the resulting home and award a glazed red tile with Wright's signature engraved. That was the official recognition that you had a Frank Lloyd Wright home. Perhaps with all the litigation (such as with the Jean-Michel Basquiat authentication committee) the foundation is scared to get involved.
I saw Riverrock over Christmas when it was 95% complete, and it does look really cool. Similar in a lot of ways, especially the living room, but quite a different floor plan. I hope the doors are a bit wider than the Louis Penfield house on the same site; even folks of normal width have to rotate sideways. Toilet in a narrow alcove, narrow cushions on the furniture, etc. Absolute commitment to design integrity, not always comfortable. Still a fascinating place to stay.
