Holy crap, check out this house. It’s 5 story house with each story about 8 feet wide. I would feel claustrophobic living in this house. Neverthless, it’s a beautiful, creative design great for metropolitan cities like San Francisco or New York.
Four wooden floors between two existing walls, hanging in a steel skeleton, organize this house: downstairs for work, dining on 1st, relaxing on 2nd, sleeping on 3rd, and on the roof, go and enjoy the view.
The border to the outside is only glass. Transparency not only a necessity, but also a trump card.
