High-rise building

A high-rise building is defined variously as a building in which:

The number of storeys means occupants need to use a lift to reach their destination
The height is beyond the reach of available fire-fighting equipment.
The height can have a serious impact on evacuation.

Typically this is considered to include buildings of more than 7-10 storeys or 23-30 m.

A low-rise building is one which is not tall enough to be classified as high-rise.

Other definitions of buildings in relation to their height include:

Mid-rise buildings of five to ten storeys, equipped with lifts.
Skyscraper of 40 storeys or more.
Supertall buildings exceeding 300 m.
Megatall buildings exceeding 600 m.
Groundscrapers that extend horizontally over a large distance while only being of a low to medium height.
Super-slender buildings which are pencil-thin and of 50-90+ storeys.
