Shanghai World Financial Center

The Shanghai World Financial Center has been intermittently under construction in Shanghai, work having resumed in 2003 after concerns about stability of the soil. It originally began construction in 1997.

Its roof height has been set at 492 m (1,614 feet), which on completion in 2007 is expected to make it tallest in the world. Architect William Pederson has resisted suggestions to add a spire that would surpass that on Taipei 101 and perhaps the Freedom Tower, calling the Shanghai WFC a "broad-shouldered building".

Its most distinctive feature is the hole through the top, above which tourists will be able to walk indoors and outdoors.
