Sky City will soon replace the Burj Khalifa as the world's tallest building, as China plans to one-up Dubai's structure in just 90 days, Business Insider reported.
The tower will be 220 stories and 383 feet high — a mere 10 meters higher than the Burj — and boast a capacity of 70,000 to 120,000 people, according to Next Big Future.
Chinese construction company Broad Sustainable Building (BSB) will construct the residential, commercial and retail space in Changsha, the provincial capital of Hunan Province, Wired reported.
BSB has plenty of experience with speedy building projects: they have built three-story building in nine days and a 30-story hotel in just 15 days, both in Changsha, according to Business Insider.

The building will include a hotel, school, hospital, offices, shops, and restaurants, which will be accessible via 104 elevators, Forbes reported.
BSB plans to use prefabricated materials built at its' factory over around four months, which will then be assembled in two months on site, according to Business Insider.
For some points of comparison, New York's Empire State Building took 410 days to build from start to finish, and the Burj Khalifa took six years days between construction beginning in 2004 and its opening in January 2010. Sky City is set to open in January 2013.
The structure will cost four billion Yuan, or about $628 million, according to Forbes. Dubai’s Burj Khalifa cost an estimated $1.5 billion.

However, some are skeptical about the building's integrity.
"So far, Sky City does not look like a winner," wrote Forbes' China correspondent Gordon Chang. "Broad originally planned a 666-meter skyscraper, but the local government wanted the world’s tallest. That’s a dead giveaway politics are distorting the economics of the project."
BSB signed an agreement last week with local district authorities in Changsha, Inhabitat reported, but it is still awaiting approval from the central government.
