The world’s tallest building took five years to reach its 828-meter, 2,716-foot height, but a Chinese company wants to leave the Burj Khalifa in the dust. Broad Sustainable Building, which already built a hotel in two weeks, aims to erect the new Sky City skyscraper within three months.
The 220-story building would be the tallest in the world by 10 meters, according to CNN, which first reported on the construction plans. It was designed by a Dubai architect, in an interesting twist. The company would use pre-fabrication methods to construct it in record time — 95 percent of the building will be built before the ribbon is cut at the ground-breaking ceremony.Despite its gargantuan size, the building will supposedly use one-fifth the energy of a traditional edifice, because its 6-inch-thick walls and quadruple-glaze windows will provide better insulation. When it’s complete, 104 elevators will connect 220 floors and 1 million square meters (10.7 million square feet) of usable space. This will include the world’s tallest hotel, living space and potential office space.
