Constructing a skyscraper once took months if not years to build. But not anymore, and certainly not in China.
In this recently released time-lapse video, a 30-story hotel is built in just 15 days, or 360 hours.
Constructed in Dongting Lake in Hunan province, the hotel is 170,000 square feet and can withstand a 9.0 earthquake reports Treehugger.
According to the International Business Times, the prefabricated modules were put together in a factory and then placed on steel structures at the construction site.
The Chinese company behind the speedy design and building is Broad Group, a firm which previously built the 15-story Ark Hotel in Changsha, China, in just six days.
