China developer to build world’s tallest skyscraper at breakneck speed

The international construction community is abuzz with the news that a Chinese developer, Broad Sustainable Building (BSB), claims that it will build an 838m-tall skyscraper in just 90 days using prefabricated materials built offsite.

BSB has recently denied rumours in the Chinese media that construction will take 210 days. The building in the southern Chinese city of Changsha will be called SkyCity One and will be 10m taller than the Burj Khalifa in Dubai, which took almost 6 years to build and is currently the tallest manmade structure on the planet.

The project is expected to cost four billion yuan and BSB says SkyCity One will contain 1.6 million m2 across 220 storeys, containing a mix of residential, commercial and retail space and capacity for more than 31,000 people. In January, using the same construction methods planned for SkyCity One, BSB built a 30-storey hotel in Hunan in just 15 days.

The company says this breakneck target will be met because 95% of the building will be built offsite using prefabricated modular technology before they have even broken ground on site.
