China plans to build world's tallest skyscraper in 90 days
A construction company in China has 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 move.
According to the Daily Mail, 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.
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 stories 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, the report said.
Despite concerns about its structural rigidity, Broad Group said that building will be able to withstand a magnitude 9.0 earthquake.
China-based Broad will employ 3,000 workers for the project.
Sky City is expected to cost around 400 million pounds, significantly less than the 940 million pounds 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.
