A video of a ten-storey building being built in just over a day has captured the attention of internet users worldwide. The video shows the erection of the large residential skyrise building in Changsha, Hunan Province, China.

Assembled by a small crew of builders and several cranes, the multi-level housing block was erected in an astonishing time of 28 hours and 45 minutes. And the construction firm behind the seemingly impossible task, Broad Group, says it can build even larger structures.

The secret to the Changsha-based construction firm’s incredible speed is prefabricated modular construction that is then shipped to its destination. When the module leaves the factory floor, over 95% of the entire construction process is complete and its dimensions are almost that of traditional shipping containers, making getting the building materials to site far easier and faster.

Complete with steel framework, walls, wiring, air conditioning, windows, insulation and glazing, each module is fitted with everything a modern room requires. Depending on the size of the project, several modules would be sent to the building site, stacked, bolted and secured to one another, and finally connected to the energy and water grids.

Representatives at the Broad Group believe that the ceiling for the number of floors it could build is as many as 200 – the Burj Khalifa, the planet’s tallest single-standing building, has 163 floors in comparison. Also, construction of these modular buildings will not be limited to housing; they say they can build everything from hospitals to hotels in a similarly impressive time frame.

The modular buildings are strong and sturdy and once assembled, earthquake-resistant, according to company officials. Each structure can be disassembled with the same ease as the assembly process, making relocation a possibility. Company representative, Daniel Zhang, told the media that his company’s efforts had turned the concept of fixed real estate into “moveable property”.

While there is no word on official pricing, the digital publication Tree Hugger, estimates that a 20-unit residential apartment block is roughly $3 million – an exceptionally cost-effective amount.
