Shanghai World Financial Center - Architecture

Architecture

The most distinctive feature in the design of the building is a trapezoid aperture at the peak. The original design specified a circular aperture, 46 m (151 ft) in diameter, to reduce the stresses of wind pressure, as well as serve as a subtext for the design, since "Chinese mythology represents the earth with a square and the sky with a circle". It also resembled a Chinese moon gate due to its circular form in Chinese architecture. However, this initial design began facing protests from some Chinese, including the mayor of Shanghai, Chen Liangyu, who considered it too similar to the rising sun design of the Japanese flag. Pedersen then suggested that a bridge be placed at the bottom of the aperture to make it less circular. On 18 October 2005, KPF submitted an alternative design to Mori Building and a trapezoidal hole replaced the circle at the top of the tower, which in addition to changing the controversial design, would also be cheaper and easier to implement, according to the architects. Foreigners and Chinese alike informally refer to the building as the bottle opener, as some also find the Kingdom Centre in Riyadh. In fact, metal replicas of the building that function as actual bottle openers are sold in the observation deck gift shop.

There are three observation decks in Shanghai World Financial Center. The height of the lowest observation deck (观光大厅) is 423 m (1,388 ft), on the 94th floor, the second is 439 m (1,440 ft) high, on the 97th floor, named "Observatory Bridge" (观光天桥), and the highest (观光天阁) is 474 m (1,555 ft) high, on the 100th floor. Admission fees range from RMB100 (US$15.40) for the 94th floor only, to RMB150 (US$23.10) for all three observation decks.

The skyscraper's roof height is set at 492 m, and has temporarily claimed the highest roof in the world. Before construction resumed on the roof, tower height was scheduled to be 509.2 m (1,671 ft) so the building would hold the title of the world's tallest building (structural top) over the Taipei 101, but a height limit was imposed, allowing the roof to reach a maximum height of 492 m. Architect William Pedersen and developer Minoru Mori have resisted suggestions to add a spire that would surpass that of Taipei 101 and perhaps One World Trade Center, calling the Shanghai WFC a "broad-shouldered building". The SWFC boasts a gross floor area of more than 377,300 m2 (4,061,200 sq ft), 31 elevators, and 33 escalators.
