You read that correctly; NINETEEN DAYS. In fact, a representative for this 57-floor skyscraper stated that “three floors in a day is China’s new normal.” The tower in Changsha is referred to as the “Mini Sky City,” which is a 180,000-square-meter mixed-use building was built in record time with modular, “LEGO-like” blocks. This particular construction process claims to have required fewer materials, which significantly reduced the amount of air pollution commonly caused by dusty construction sites.
Along with that, the same rep claims the air circulated throughout the building’s interior is “99.9% pure” due to its tight envelope, built-in air conditioning system and energy-efficient quadruple-pane glass. The “Mini Sky City” tower contains 19 ten-meter-high atriums, 800 apartments, and enough office space for 4,000 people. The tower is actually only part of a larger Sky City complex which is expected to also contain a 220-story skyscraper that should reach approximately 840-meters!
