“Three floors in a day is China’s new normal,” says a representative for this 57-floor skyscraper that was built in just 19 days. Known as the “Mini Sky City” tower in Changsha, the 180,000-square-meter mixed-use building was built in record speed with modular, “LEGO-like” blocks. The process also claimed to have required less materials and significantly reduced the amount of air pollution commonly caused by dusty construction sites.

Adding to that, the representative claims the building’s interior air is “99.9% pure” due to the built’s tight envelope, built-in air conditioning system and efficient quadruple-pane glass.
The tower is comprised of 19 ten-meter-high atriums, 800 apartments, and office space for 4,000 people. It is part of a larger Sky City complex which is expected to realize a 220-story skyscraper that will reach nearly 840-meters.
