This list of skyscrapers by floor area includes the largest skyscrapers in the world, measured in square meters (m 2) and square feet (sq ft). To qualify as a skyscraper, a structure must be self-supporting, without relying on tension cables or external supports for stability, and must reach a minimum height of 150 meters (492 feet).
For example, when moving from 1.5 meters to 284 meters, the dry bulb temperature decreased by 1.85 °C while the wind speeds increased from 2.46 meters per seconds to 7.75 meters per second, which led to a 2.4% decrease in summer cooling in reference to the Freedom Tower in New York City. However, for the same building it was found that the ...
Without this vanity height, the Burj Khalifa would still be the tallest building in the world, but only exceeding the Shanghai Tower's highest usable floor by 2 meters. [1] [3] The next potentially tallest building, the Jeddah Tower, could be over 1,000 meters tall, but its highest floor is planned to be 630m above ground. The top 370m ...
The Carlton Centre has 50 floors, and is 223 m (732 ft) tall. The foundations of the two buildings in the complex are 3.5 m (11 ft) in diameter and extend 20 m (66 ft) down to the bedrock, 30 m (98 ft) below street level. The building houses both offices and shops, and has over 46 per cent of the floor area below ground level.
The tower is built upon a 185-foot (56 m) tall windowless concrete base, designed to protect it from truck bombs and other ground-level attacks. [126] From the 20th floor upwards, the square edges of the tower's cubic base are chamfered back, shaping the building into eight tall isosceles triangles, or an elongated square antiprism.

The X-Seed 4000 was a concept for a megatall skyscraper. [1] Its proposed 4-kilometre (2.5 mi) height, 6-kilometre-wide (3.7 mi) sea-base, and 800-floor capacity could accommodate 500,000-1,000,000 inhabitants. This structure would have been composed of over 3 million t (3.3 million short tons) of steel.
