The Largest Building Ever Constructed Has Opened in China

At what point does a building become a city? At 1.7 million square meters, the New Century Global Center lands somewhere between the two.

New Century, which has been under construction since spring of 2012 (which isn't long, for a building of this size), opened officially on July 1. The 18-story, glass-and-steel frame structure sits above a new subway station in Chengdu, a Sichuan province city of more than 14 million and one of China's fastest-growing megalopolises.
