With the use of modular pieces, Chinese builder BSB completed a 57-floor mixed-use tower in just 19 days, saying that “three floors in a day is China’s new normal.”

Inhabitat names it “the world’s tallest prefab tower.” Official pictures and a statement are yet to be released.

The tower, called Mini Sky City, is located in Changsha, in the Southeastern Chinese province of Hunan. It is part of the Sky City complex which is to include a 220-story tall skyscraper at 2,749 feet, but is yet to be completed,

According to Sploid, the construction company used 2 million-sf worth of modular blocks they manufactured themselves that are energy efficient. The tightly sealed blocks ensure an efficient use of HVAC systems, as well as protection from outside pollution.

A representative of the company told Sploid "that the use of modules reduced the use of concrete by 15,000 trucks, [which] almost eliminated all the release of dust in the air."

Mini Sky City has 19 atriums that are 33 feet tall each. It has the office space capacity for 4,000 employees, as well as residential units for 800 households.
