The secret of the company that built the skyscraper 57-storey Sky City Mini, is a special technology. Namely, the assembly of the building is made of steel modules. Simply put, the tower was founded by the LEGO designer principle of factory-produced blocks. The use of ready-made structures reduces the need for concrete, for deliveries that will require at least 15,000 trucks. The skyscraper has an area of 180 thousand square meters. There will be 800 apartments, as well as large office space for 4 thousand people. This speed does not affect the quality of work. Modular skyscrapers are stable even up to a magnitude 9 earthquake!.
One of the most important features of the building, unlike other high-rise buildings in Changsha, is the active use of "green" technology. For example, use three air purification both indoors and outdoors. And the four-tiered double-glazed windows can reduce the release of carbon dioxide into the air by about 12 tons compared to other skyscrapers of the same size. Steel module construction technology, developed by BSB engineers, has been used previously. The tallest building is a 30-storey hotel in Hunan, which is assembled 15 days in 2012. So the cost of building a high square meter is about $ 1000. The company will not stop at this, and plans to build a 200-storey skyscraper in 90 days
