A construction company has revealed plans to build the world’s tallest skyscraper – in just three months.
Sky City will be a 220-storey structure which stands at an incredible 838m in Changsha, south-east China.
It will house 17,400 and also boast hotels, hospitals, schools and office space with occupants using the 104 high-speed lifts to get around.
The half-mile high superstructure will be ten-metres taller than the Burj Khalifa in Dubai – the current tallest building.
And it will dwarf the Shard in London by standing more than 530-metres above the western Europe’s tallest building.
But the most impressive thing about Sky City is that its designers, Chinese-based Broad Group, plan to start and finish it in just 90 days.
This astonishing pace, which will see five storeys go up a day, is down to the revolutionary method of prefabricated building where blocks are built off site and slotted together to save time.
Despite concerns about its structural rigidity, Broad Group says the half-mile high building will be able to withstand a 9.0 earthquake.
The idea isn’t pie in the sky thinking either, with Broad making headlines last year when they built a 30-storey building in 15 days.
China-based Broad, which started out making air-conditioning systems in the 1980s, will employ 3,000 workers for the project.
Spread over 1 million square metres and be made up of 200,000 tonnes of steel, Sky City will be a mini town when completed.
It will have more than 5,000 residential properties playing home to 17,400 residents as well as a hotel for 1,000, a hospital, five schools and office space with overall capacity standing at 31,000.
Sky City is expected to cost around £400 million, significantly less than the £940 million Burj Khalifa which took more than five-years to build.
Broad is still awaiting final approval from the Chinese government, but it is hoping the project will get off the ground towards the end of December and be completed before April 2013.
