The Changsha Broad Air Conditioning Company has unveiled plans to build the world's second-tallest building in China.
The company will apply its self-developed technology system to design and build the 666m sustainable building.
The sky city will feature residential apartments, offices, shops, restaurants, film theatres, schools, hospitals and other facilities.
The 200-storey building will have a building area of 1.2 million square metres and can accommodate 70,000 to 110,000 residents.
All the building parts will be designed and manufactured at a factory before being assembled at the construction site, according to peopledaily.com.
The current tallest building in the world is the Burj Khalifa, located in Dubai.
