“Sky City One, is a proposed supertall skyscraper approved for construction in the city of Changsha, Hunan in south-central China, to be constructed by the Chinese construction company Broad Group.
If built as planned and to schedule, Sky City would be likely to be the tallest building in the world at the time of its completion, with 220 floors and a total height of 838 meters. The construction plan calls for it to be built from pre-fabricated units constructed on site in an unprecedentedly short period of 210 days. BSB’s plan is to assemble 95% of the building in its factory before a single shovelful of dirt has been moved at the actual build site.

As of October, BSB has received approval from the government and has stated that they are still going to begin construction in November. This puts the date of completion at May 2013.”

With its revolutionary architecture, the Sky City Tower should consume only one fifth of the energy of an equivalent conventional building. BSB has made quadruple glazing and exterior walls of 15 cm thickness to improve thermal insulation.

The use of new materials and construction method can make substantial savings: the total investment for the project of the Sky City Tower is $640 million, against 1.52 billion for the Burj Khalifa and 2.21 billion for the Shanghai tower.

So far, Broad has built 4 demos of BSB, including: the 6-story Broad Pavilion in Shanghai Expo 2010 in 1 day, the 14-story New Ark’s Hotel in Broad’s headquarters in 6 days, the Broad Pavilion in 2010 United Nations Climate Change Conference in 8 days and a 30-story hotel prototype near Dongting lake in 15 days.
