Skycity

Sky City (Chinese: 天空城市; pinyin: tiānkōng chéngshì), or Sky City One, is an 838 m (2,749 ft) tall skyscraper proposed for construction in the city of Changsha, Hunan in south-central China. The prospective builders, Broad Sustainable Building, estimated it would take just 90 days to construct, but other estimates state that it will take 210 days to complete. If completed, it could become the tallest building in the world.

Broad Sustainable Building, who specialise in making buildings that are sustainable, cost less, use environment friendly materials and can be built in a short amount of time, using techniques like prefabrication, had intended to build a 666 m (2,185 ft) tall skyscraper, but the local government wanted the world's tallest building, hence the current plans. The company has constructed 20 buildings in China using the same method and has several franchise partners globally. The Broad Group have previously concentrated on manufacturing large air-conditioners, being among the world leaders in solar air-conditioning, before they shifted to constructing environment-friendly buildings. All employees of the group must follow a manual issued by the company chief Zhang Yue, which contains tips on energy-conservation. He also was awarded the Champions of the Earth award by the United Nations in 2011 for his contributions towards the environment.
