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.
Saudi Arabia knows how to keep up with the Joneses. The Burj Khalifa in Dubai has officially been the world's tallest building since its opening early last year, but by 2016-ish Saudi Arabia plans to let the UAE know exactly who the big brother is on the Arabian Peninsula. The Saudis have inked a deal between the Kingdom's holdings company and a certain Bin Laden Group to build the world's tallest building, an elegant yet extreme tower that will rise 3,281 feet above the streets of Jeddah.
