The new building is being touted as a “vertical city” that will be able to accomodate up to 30,000 people at a time.
When it’s completed, the 220-storey skyscraper will stand just over 8 metres taller than the current tallest, the 829.9 metre Burj Khalifa in Dubai, which opened in 2010.
The project leaders say they’ll use revolutionary construction techniques to build the tower in just three months, after four months of pre-construction work.
The tower will feature 92 elevators, 56 courtyard parks and recreation spaces, and 86,000 square metres of indoor organic farms.
As well as the elevators, residents can use a 9.6 kilometre ramp that runs from the first to the 170th floor.
Sky City will be five times more energy efficient than other skyscrapers, thanks to a built-in power plant that recycles waste heat from activities inside the building.
