Japanese architect Shigeru Ban won the prestigious Pritzker Prize in 2014 for his innovative use of materials and his humanitarian projects. In 1995 he founded the NGO Voluntary Architects' Network (VAN) dedicated to disaster relief, and is particularly known for his recycled paper tube structures used to build post-disaster temporary housing. His work encompasses aspects of modernist, Japanese and rationalist architecture, and his formal explorations with humble building materials have led to unique structural solutions implemented in private residences, churches, and museums across the world.
