The company has honed its technology to accelerate its construction speed from two floors to three floors a day, he said. The first 20 floors were completed last year, and the remaining 37 were built from Jan 31 to Feb 17 this year, Mr Xiao said. The Changsha-based company spent four and a half months fabricating the building’s 2,736 modules before construction began.

The structure is safe and can withstand earthquakes, Mr Xiao said. Mini Sky City, which has 19 atriums, 800 apartments and office space for 4,000 people, goes on sale next month. “People nowadays want more personalized architecture.” “But it is not perfect, and it does not meet all kinds of personalised demands,” Mr Liu said. Mr Liu Peng, associate director of the engineering consulting firm ARUP Beijing, said the method is worth developing because it could become a safe and reliable way to build skyscrapers rapidly. Some critics say the method could lead to cityscapes with overly uniform architecture. Such modular approaches have been used for high-rise apartment blocks elsewhere, including in Britain and the US. “With the traditional method, they have to build a skyscraper brick by brick, but with our method, we just need to assemble the blocks,” company engineer Chen Xiangqian said. Its time-lapse video of the rapid assembly has become popular on Chinese video-sharing sites since it was first uploaded on YouTube. The company, which has ambitions to assemble the world’s tallest skyscraper at 220 floors in only three months, worked on Mini Sky City in two spurts separated by winter weather. The Broad Sustainable Building put up the rectangular, glass-and-steel Mini Sky City in the Hunan provincial capital of Changsha using a modular method, assembling three floors per day, company vice president Xiao Changgeng said. CHANGSHA (CHINA) - A Chinese construction company is claiming to be the world’s fastest builder after erecting a 57-storey skyscraper in 19 working days in central China.
