However, in China, the land where entire cities can be built with the snap of a finger, skyscrapers are now going up at breakneck speed with the use of prefabricated materials. Broad Sustainable Building, a Chinese construction company, has made headlines over the last week for completing a 57-story tower in just 19 days, reports Gizmodo.

The 2-million-square-foot tower, located in the city of Changsha, was erected at a pace of 3 floors per day and will provide office space for 4,000 people and 800 apartments. Broad has called the construction method “the most profound innovation in human history."
