Student homes

In high school, when I was 17, we got this assignment for architecture class to design student homes. The assignment gave us cubes of 6 m sides and we should do the interiors. I wanted to use another shape than a cube, and the teacher agreed, but then I also had to do the construction of the building. This is what I came up with. (reconstructed in POVray . We didn't have computers in 1977.)
