And as this time-lapse video shows, the 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. It was originally planned to be built up to a height of 220 storeys, but it was cut down because of concern it was too close to a nearby airport
The prefab construction, which has 19 atriums which are each 10 metres tall, is also environmentally friendly, claims the developer, as large sections were put together at another location 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.In all, 15,000 fewer truck journeys were made, greatly reducing dust and fuel pollution.
The building was also constructed with China's pollution problem in mind, using quadruple-thick glass and tight '99.9 per cent sealed' construction.
The company behind the construction, Broad Sustainable Building, previously built a 30-storey building in Changsha in just 15 days.
Broad claims that its technology is 'the most profound innovation in human history'.
While the rapid construction is eco-conscious, some online users have raised concern over safety.
