What is the tallest building in the world?

When its construction is completed, the Burj Dubai skyscraper in the United Arab Emirates will be the world’s tallest skyscraper at 2,064 feet (629 meters) high. As of early 2009, the world’s tallest completed skyscraper was still the Taipei 101, located in the Hsinyi district of Taipei, Taiwan. With 101 stories, it reaches 1,671 feet (509 meters) high. Taipei 101 became the world’s tallest building when it was finished in 2003, surpassing the Petronas Towers in Kuala Lumpur, Malaysia, the world’s tallest twin towers. The Sears Tower in Chicago, Illinois, is the world’s third tallest building that people can live and work in. Built from 1970 to 1974 for Sears, Roebuck & Company, it rises 110 stories to a height of 1,450 feet (442 meters). (If you count the tower’s antenna, it actually reaches 1,730 feet [527 meters]) high. Another very tall structure (though it is not a skyscraper building where people can live and work) is the CN Tower in Toronto, Canada. This transmission tower is 1,815 feet (553 meters) tall and was built in 1976.
