Why You Can't Be Blasé About the Next World's Tallest Building

Architects and record-keepers had been waiting for months to learn the status of Broad Group's "Sky City," a 220-story skyscraper that was supposed to be built in just 90 days this winter in the Chinese city of Changsha. Thirty feet higher than the Burj Khalifa and constructed of pre-fab modules, the prospective tower languished in government-approval limbo.

The wait is over: the title of world's tallest building really will be transferred from oil-rich Dubai to this mid-sized provincial Chinese city. Last week, Broad Group announced it has received approval from the Chinese government and will break ground on the project in August, though according to Quartz's Lily Kuo, Broad Sustainable Building has pushed the building's schedule to a more modest seven months.
