The Council on Tall Buildings and Urban Habitat (CTBUH) defines a ‘megatall’ building as one that is more than 600 m (1,968 ft) in height. This classification exceeds ‘supertall’ buildings which are those exceeding 300 m (984 ft) in height.
The widely recognised CTBUH criteria for determining the height of a building is the ‘…lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flagpoles or other functional-technical equipment.’
As of February 2016, only 3 megatall buildings had been completed:
As the CTBUH has said, this is the ‘era of the megatall’. They estimate that the number of buildings classified as megatall will have risen to 7 by 2020 with the following projects having been completed:
- Ping An Finance Centre, Shenzhen.
- Greenland Center, Wuhan.
- Signature Tower, Jakarta.
- Kingdom Tower, Jeddah.
