A developer in China has built an entire 57-story building in just 19 days.
Mini Sky City building was put up brick by brick – at a rate of three full storeys a day – in Changsha, the capital of Hunan Province in south-central China.
The building has 800 apartments and enough office space for 4,000 people.
The construction is also environmentally friendly, claims the developer, as large sections of the building were built off-site and taken to the building site to be stacked on top of each other.
This significantly reduced the number of trips needed to transport the raw materials. They said that, with a total of 15,000 truck journeys less than would usually be needed to transport concrete, it had reduced dust and fuel pollution.
The building was also constructed with China’s pollution problem in mind, using quadruple-thick glass and tight “99.9% sealed” construction which prevents outside pollution entering homes.
The company behind the construction, Broad Sustainable Building, previously constructed a 30-storey building in Changsha in just 15 days.
The company claims that its technology is “the most profound innovation in human history”.
While the rapid construction is eco-conscious, concerns over safety have been raised.
Key statistics:
• 57 storeys
• 19 atriums, each 10 m tall
• Office space for 4,000 people
• 800 apartments
• 19 days to build
