Sky Garden House by Guz Architects. Wierd, but I think it would be really nice to inhabit. It's also an interesting application of green roofs/roof gardens to a very modern, otherwise steel and concrete design.
I can't believe they only have a one boat "garage".I definitely would have a two or three boat garage. One for the houseboat, one for the pontoon boat, and one for the speed boat and jet skis.-)exactly my vidion of a house in key west
