The very idea that a 30-story building could be built in 15 days -- or 360 hours -- is mind-boggling. But that's what happened in China, as a 30-story hotel went up in just 15 days.

(See the time lapse video below.)

It was built in the Hunan Province of China, near Dongting lake, by Broad Group. The Chinese construction company specializes in sustainable architecture, and prefabricated modules placed on steel structures.

Reports suggest the 30-story hotel built in 15 days is sturdy enough to stand up to a magnitude-9.0 earthquake. The hotel is also reportedly energy-efficient and more solid all the way around than one might surmise. But the most interesting fact of all remains: It is a 30-story building that was built in 15 days.
