The Cardboard Cathedral, constructed as simple A-frame structure from 98 equally sized cardboard tubes and 8 steel shipping containers, is said to be one of the safest, earthquake-proof buildings in Christchurch, New Zealand. Aside from the building’s structural integrity, each paper tube is coated waterproof polyurethane and flame retardants while protected by a semi-transparent, polycarbonate roof.
Shigeru Ban, who has been developing the recycled tubes as an emergency relief building material since 1986, declared that “the strength of the building has nothing to do with the strength of the material.†He stated, “Even concrete buildings can be destroyed by earthquakes very easily, but paper buildings cannot.†[Arch Daily]
