From emergency relief shelters to a cardboard cathedral and exhibition spaces in shipping containers, Pritzker prize-winning architect Shigeru Ban has made his name with his restlessly inventive response to material and situation, as much as with his humanitarian work at the sites of natural and man-made disasters. In the spirit of a three-dimensional poetry, Ban uses materials as an incorporated part of his design, selected not for their cutting-edge credentials but rather for their expressive ability, their capacity to convey the building's overall concept.
