Product Description
High Quality Content by WIKIPEDIA articles! The world’s tallest structure is the 828 m (2,720 ft) tall Burj Khalifa in Dubai, United Arab Emirates. The building gained the official title of “Tallest Building in the World” at its opening on 4 January 2010. It is taller than any other man-made structure ever built. The Council on Tall Buildings and Urban Habitat, one organization that certifies buildings as the “World?s Tallest”, recognizes a building only if at least fifty percent of its height is made up of floor plates containing habitable floor area. Structures that do not meet this criterion, such as the CN Tower, are defined as “towers”.
