In 1994, after seeing photographs of the plastic sheets given to Rwandan refugees as protection from the elements, Shigeru Ban went to the United Nations High Commissioner for Refugees to propose ideas for better shelters. His temporary housing has employed everything from plastic beer cartons to paper tubes to create ingeniously flexible spaces. By sourcing unconventional, recycled, inexpensive, local and sustainable materials, he stimulates devastated economies by involving local resources and labour. This volume is the first book-length study to collect, catalogue and examine these works.
