This mindblowing video from the Dongting Lake region in China shows an incredible timelapse of a prototype Green building being erected in just 15 days using a modular approach. The building offers a magnitude 9 earthquake resistant honeycombed structure, energy efficient insulation and an extensive air filtration system (Due to the air pollution problems that the country is facing). Its pretty damn incredible to watch a building go up that fast. I'm just left wondering how long the planning phase alone for this building took.
