Bare-all walls

In a highly populated city like Tokyo, you would expect living spaces to be confined, but a Japanese architectural firm has turned that on its head by designing a house you can literally see through.

Using glass and white steel frames, Sou Fujimoto's House NA is transparent from front to back and comprises 21 individual floor plates at various heights, linked by stairs and ladders that can be cordoned off with curtains.

Fujimoto claims to have drawn inspiration from the open-space communal living of ancient predecessors who inhabited tree branches.
