World’s Tallest Building

At present, the Burj Dubai, or Dubai Tower, is 1,853 ft. high (564.9 m) with 152 completed floors. That makes the Burj Dubai the tallest freestanding structure in the world, until now a title held by the CN Tower in Toronto. To give American readers a sense of scale, the Sears Tower, the tallest building in the U.S., is 1,730 ft tall, including the antenna. While the finished height of the tower is officially being kept a secret in order to discourage competitors for the title of world’s tallest building, reports indicate that the tower will exceed 2,121 ft., making it the tallest structure ever built.
