Renowned Japanese architect Shigeru Ban can be called a leader in the paper architecture movement.Far from being flimsy or gimmicky, his structures provide real solutions in terms of cost, eco-friendliness, and portability. Ban’s buildings can be erected by amateurs with no heavy machinery, sometimes in a matter of just hours. His incredible ideas were put to use after the 1995 earthquake in Kobe, Japan to provide temporary homes and churches to displaced residents.
