The Chinese construction company Broad Sustainable Building recently announced plans to start construction on the next world's tallest building later this year in Changsha, Hunan Province. The building is planned to be an 838-meter, 220-story tower of residential, office and commercial space that, if built, would replace the 828-meter Burj Khalifa in Dubai as world's largest building. The company plans to begin construction in November.

The height is impressive on its own. Compounding that feat is the company's timeframe for building this behemoth: 90 days from groundbreaking to ribbon cutting. The speed is mainly due to the fact that most of the building will be pre-fabricated. As ABC News reports, 93 percent of the building's construction will be completed before ground is even broken. This slideshow from Treehugger has a nice breakdown of the pre-fabrication and construction process.
