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, although the Home Quality Mark defines high rise as a building that is 18 meters or over (the height historically linked with the reach of fire and rescue service equipment) and this height has also been adopted by guidance following the Hackett Review.

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:
