After the 1995 Kōbe earthquake, Shigeru Ban developed cardboard tubes that could be used to quickly construct refugee shelters that were dubbed "Paper Houses". Also as part of that relief effort he designed a church using 58 cardboard tubes that were 5m high and had a tensile roof that opened up like an umbrella. The church was erected by Roman Catholic volunteers in five weeks. For the Nomadic Museum, Ban used walls made of shipping containers, stacked four high and joined at the corners with twist connectors that produced a checkerboard effect of solid and void. The ancillary spaces were made with paper tubes and honeycomb panels. The museum was designed to be disassembled and it subsequently moved from New York, to Santa Monica, Tōkyō and Mexico.
