A Chinese company, Broad Sustainable Building, plans to build the tallest building in the world — in just 90 days.


It’s called Sky City, and engineers say it will be the tallest skyscraper in the world — at 2,749 ft and 220 floors — by the end of March of 2013, according to a recent article published on



The article says the skyscraper, which will rise in Changsha city, will be built at a rate of five floors per day. This incredibly fast construction rate will be achieved by using a prefabricated modular technology developed by Broad, which has built 20 tall structures in China, including a 30-story hotel in 15 days.

The project will use 220,000 tons of steel.


According to the article, foundation work will begin at the end of the month, once the Chinese authorities give the final go-ahead to the project.
