Library for a poet, by Shigeru Ban,1991 - in Kanagawa, Japan
This library was built as an annex to a house and was influenced by the Odawara Pavilion, which the owner had seen. He felt that a paper library would be best suited to house paper books. The paper tubes used in the library are 100mm in diameter and 12mm thick. Post-tensioned steel wires were used for the spanning sections. The four floor to ceiling bookshelves along the sides of the room are structurally independent of the paper tubes and are cantilevered off the floor, absorbing the horizontal load. The bookshelves, which contain insulating material and have an exterior finish, were fabricated separately at a factory.
