China’s Sky City set to become the world’s tallest building

Broad Sustainable Building (BSB), the Chinese property development company, intends to construct the world’s tallest building in Changsha within just three months, representatives have revealed.

It equates to a build rate of approximately five storeys per day, an astonishing feat were it not for the country’s talent for producing pre-fabricated properties.

‘Sky City’ will measure in at 838m, 10m taller than the current record holder, the Burj Khalifa in Dubai which took five years to build and is yet to accomplish full tenancy. It will be the 17th project to be completed by BSB, who have previously constructed a 30-story hotel in only 15 days.

When completed Sky City will house 17,400 people as well as office space, hospital, hotel and school. It will require over 100 high-speed elevators and be able to withstand a magnitude 9.0 earthquake.

The £400 million pound project will use a revolutionary ‘prefabrication’ building method to enable the project to be completed in a staggering 90 days. Sky City will employ several thousand workers and is set to only cost half as much as the Burj Khalifa.

Despite the ongoing drive to build the world's biggest properties, Hong Kong and the Burj Khalifa provide evidence that such projects can offer unexpected difficulties in achieving full tenancy.
