Esplanade - Theatres on the Bay, Singapore
The striking Esplanade - Theatres on the Bay waterfront building cost some $600 million to build and helped cement Singapore's place among architecturally cutting-edge Asian cities. The spikey structure has been likened to everything from a durian fruit to a fly's eyes. In fact, the "spikes" covering the exterior serve as sunshades -- a helpful addition given Singapore's steamy climate. The building contains a concert hall, theater, public library and outdoor performance space.
