Casa Biblioteca in Brazil

 This is a beautiful home...

So the house is set in the forest and steps own a hill. The lowest level, with the big volume(above and below) is the traditional "Living / Dining / Kitchen" open plan living. One level up is a library of books, and up from that is the bedroom. 

The roof is ground level at the entrance (you go down the steps in the center below) and the roof is a deck that appears to float above a lily pond that surrounds the roof edge. I am sure it is all kinds of violations of USA code (safety and railings on the roof, ADA access. etc) - but it is lovely.

Because the supports are set in a bit, not at the edges, it looks very much like the roof is floating above the house.
