The Shanghai World Financial Center (SWFC) is a supertall skyscraper located in the Pudong district of Shanghai, China. It was designed by Kohn Pedersen Fox and developed by the Mori Building Company. It is a mixed-use skyscraper, consisting of offices, hotels, conference rooms, observation decks, and ground-floor shopping malls. Park Hyatt Shanghai is the hotel component, containing 174 rooms and suites. Occupying the 79th to the 93rd floors, it is the second-highest hotel in the world, surpassing the Grand Hyatt Shanghai on the 53rd to 87th floors of the neighboring Jin Mao Tower. On 14 September 2007, the skyscraper was topped out at 492.0 meters (1,614.2 ft), making it, at the time, the second-tallest building in the world and the tallest structure in Mainland China. It also had the highest occupied floor and the highest height to roof, two categories used to determine the title of 'world’s tallest building'. The SWFC opened on 28 August 2008, with its observation deck opening on 30 August. This observation deck, the world's tallest at the time of its completion, offers views from 474 m (1,555 ft) above ground level. The SWFC has been lauded for its design, and in 2008 it was named by architects as the year's best completed skyscraper. The SWFC will be exceeded in height by the adjacent Shanghai Tower, which is due for completion in 2014.
