Japan Pavilion in Hanover, Germany, 2000 Shigeru Ban Architects, Tokyo, Japan
Shigeru Ban collaborated with architect Frei Otto to design a gridshell structure 72 m (235 ft) in length. The tunnel-arch geometry was primarily made out of paper tubing. After Expo 2000 concluded, the structure was recycled to paper pulp.
