A developer in China built an entire 57-story mixed-use building brick by prefabricated brick at a rate of three full stories a day. The building took only 19 days to complete, according to Gizmodo.
The building has 800 apartments and enough office space for 4,000 people. It was originally planned to be built up to a height of 220 stories, but it was cut down because of concern it was too close to a nearby airport.
The building was also constructed with China’s pollution problem in mind, using quadruple-thick glass and tight “99.9% sealed” construction.
