Attic are some of the most interesting parts of a building. It is the area where we are the closest to the sky. This often means some of the best views as well as the most intense heat in the building. They also offer a unique way for us to interact with the structure of the building, creating interesting forms and shapes that make for unique, more playful spaces.
I'd love to have this kind of hammock in my garden someday. I would make it much "happier" though. More colors, twinkle lights and/or chinese lanterns, and higher, less contemporary, foliage would surround mine. ;]
