The National Taichung Theater in Taiwan was designed by Japanese architect Toyo Ito to resemble a coral reef. It has three theaters within organically sloping halls formed by a three dimensional grid that has been sculpted into an irregular shape. The curved concrete walls were poured into a prefabricated steel cage and hand-plastered. Ito drew inspiration from natural formations like rocks and caves to create a building that provides a soft respite within the city through its symbiotic relationship with nature.
