Paper House, by Shigeru Ban, 1995 - in Lake Yamanaka, Yamanashi, Japan
An S-shape configuration comprised of 110 paper tubes defines the interior and exterior areas of the paper house. The large circle formed by the interior tubes forms a big area. A freestanding paper tubes column with a 1.2m diameter in the surrounding gallery contains a toilet. The exterior paper tubes surrounding the courtyard stand apart from the structure and serve as a screen. The living area in the large circle is without furnishing or detail other than an isolated kitchen counter, sliding doors, and movable closets. When the perimeter sashes are opened, the roof, supported by the colonnade of paper tubes, is visually emphasized and a spatial continuity is created between the surrounding gallery space and the outdoor terrace.
