A villa built as a permanent structure using paper tubes which are 2.7 meters long, 15 millimeters thick with a diameter of 28 centimeters. On a lot which is ten meters square, 80 structural paper tubes form a circle. A kitchen counter and a movable closet are placed inside this circle, and the peripheral space functions as a corridor. Another 30 paper tubes surround a bathroom and a tsuboniwa (small garden), forming a smaller circle. There is a toilet made of a paper tube with a diameter of 1.23 meters in a corner of the corridor. If all sashes surrounding the house are slid open, the pure form of the structure, comprised of the room continuing to the terrace and the roof supported by the paper tubes, emerges.
