Despite the financial crisis currently rippling through the global economy, the world is in the midst of an unprecedented skyscraper boom. Architects, engineers, and developers have raced to begin building towering structures, transforming the definition of modern skyscrapers. According to the Council on Tall Buildings & Urban Habitat, a nonprofit based at the Illinois Institute of Technology, some 36 buildings have reached heights of 1,000 ft. or more, meeting the definition of "supertall" structures. The Burj Dubai, shown here, is currently the world's tallest building—and nearly 1,000 ft. taller than the famed Sears Tower in Chicago.
It remains unclear how the current global economic issues will affect the supertall trend. But frozen credit markets in developed economies may not affect developments already in progress in locations such as the Middle East and Russia. Here, then, is the council's list of the 20 tallest buildings in the world currently under construction, from supertall to supertallest.
