Just over a year ago I wrote a post about a Chinese company, Broad Group, that was able to build a 15-story hotel in 6 days, using prefabricated modules. An amazing feat, but they topped it in December 2011 by building a 30-story hotel in 15 days, finishing it on New Years Eve. And once again they made a time lapse video and put it online. According to Broad Group their building can withstand a 9.0 earthquake and is more energy efficient than regular buildings. Only in China?
