The World's Tallest Building

The world's tallest building is the 828m tall Burj Khalifa in Dubai, which gained the official title in 2010. The Council on Tall Buildings and Urban Habitat recognizes a building's height only if at least 50% is made up of habitable floors. While some towers are over 600m, only the tallest are publicly recorded. The Petronas Twin Towers in Kuala Lumpur were the world's tallest from 1998 to 2004, measured to the top of their spires. Their spires are considered architectural features, unlike antennas which can be added or removed.

Worlds Tallest Building

The world's tallest structure is the 828 m (2,717 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, an organization that certifies buildings as the "Worlds Tallest", recognizes a building only if at least fifty percent of its height is made up of floor plates containing habitable floor area.[1] Structures that do not meet this criterion, such as the CN Tower, are defined as "towers". There are dozens of radio and television broadcasting towers which measure over 600 metres (about 2,000 ft) in height, and only the tallest are recorded in publicly available information sources.

PETRONAS TOWER

he Petronas Twin Towers were the tallest buildings in the world until Taipei 101 was completed in 2004, as measured to the top of their structural components (spires, but not antennas).[3] Spires are considered integral parts of the architectural design of buildings, to which changes would substantially change the appearance and design of the building,

whereas antennas may be added or removed without such consequences. The Petronas Twin Towers remain the tallest twin buildings in the world. The Petronas's height compared to some other well-known tall structures The Willis Tower (formerly the Sears Tower) and the World Trade Center towers were each constructed with 110 occupied floors 22 more than the Petronas Twin Towers 88 floors. The Willis Tower and the World Trade Centers roofs and highest occupied floors substantially exceeded the height of the roof and highest floors of the Petronas Twin Towers. The Willis Towers tallest antenna is 247.4 ft taller than the Petronas Twin Towers spires. However, in accordance to CTBUH regulations and guidelines,[5] the antennas of the Willis Tower were not counted as part of its architectural features.[6] The spires on the Petronas Towers are included in the height since they are not antenna masts. Therefore, the Petronas Twin Towers exceed the official height of the Willis Tower by 10 m, but the Willis Tower has more floors and much higher square footage.
