It will house 17,400 people as well as offices, schools and even a hospital

Builders intend to put it up at an amazing five storeys a DAY



A construction company yesterday revealed plans to build the world's tallest skyscraper - in just three months.

Sky City in Changsha, south-east China, will be a 220-storey structure standing at an incredible 2,749ft (838m).

It will house 17,400 people and also boast hotels, hospitals, schools and office space with occupants using 104 high-speed lifts to get around.

The half-mile high superstructure will be 32ft taller than the Burj Khalifa in Dubai - the current tallest building - and is expected to cost almost half as much.

It will dwarf the Shard in London, standing more than 530m above the western Europe's tallest building and, when completed, will mean nine of the 10 tallest skyscrapers in the world are in Asia.

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 magnitude 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.

WORLD'S TALLEST SKYSCRAPERS Burj Khalifa , Dubai, UAE - 163 floors / 2,717ft



Makkah Royal Clock Tower Hotel , Mecca, Saudi Arabia - 120 floors 1,971ft



Taipei 101 , Taipei, Taiwan - 101 floors / 1,670ft



Shanghai World Financial Centre , Shanghai, China - 101 floors / 1,614ft



International Commerce Centre , Hong Kong - 118 floors / 1,588ft

China-based Broad, which started out making air-conditioning systems in the Eighties, will employ 3,000 workers for the project.

Spread over 1million 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.
