A new time-lapse video shows off the amazing feat pulled off by Chinese workmen who built a 30-storey hotel from scratch in just 15 days.
The 183,000sqft Ark Hotel in the south central Chinese city of Changsha took just 360 hours to build.
It was built on the Dongting Lake in the Hunan Province by Borad Group, a Chinese construction company specialising in sustainable architecture, according to the Daily Mail.
The mega-hotel is magnitude 9 earthquake-resistant, with a soundproofed and thermal-insulated structure, as well as air quality monitoring in every room.
All the materials and sections were built to specification off-site to minimalise waste, and workers laboured until 10pm every day to get it done.
