Paper house is a creation by Shigeru Ban to provide a temporary home (16 square meters) to several victims of the Kobe earthquake. Later they were also built in India and Turkey. These houses could be easily constructed. As foundations cases of beer (lent by the beer company) filled with sand they were used. The walls were made with paper tubes. The tonneau cover also subject to a truss cardboard, can be removed and separated in summer to allow ventilation. The tubes were waterproofed paper and stuck together with double-sided tape. As a bonus the materials used were totally recyclable.
