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 three 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 seven by 2020 with the following projects having been completed:
- Ping An Finance Centre, Shenzhen.
- Greenland Center, Wuhan.
- Signature Tower, Jakarta.
- Kingdom Tower, Jeddah.
