Impressive Time Lapse video is released by a Chinese company showing how a 57 story skyscraper is built in just 19 days using prefabricated lego blocks technology.

“The skyscraper, based in Changsha, southeast China, was fully built with energy-efficient, factory-produced blocks at the speed of three stories per day”, the Chinese Broad Sustainable Building company said.

The building is estimated to afford office space for 4,000 people and 800 households. It covers an area of almost 180,000 square meters.

Reports say that originally building was planned to be above 90 stories but it was cut short to 57 stories as there was an airport nearby. This project also has a major delay of about a year as plans were reviewed by construction officials.


China, as we all know, is densely populated and pollution is becoming a serious concern. This building company claims that air inside this building is much cleaner as compared to the air in atmosphere courtesy its tight construction and modern air conditioning system
