Building Height

How do I measure building height?

Building height can be determined by measuring the vertical distance between natural ground level to the roof or parapet at any point.

Service infrastructure including air conditioning units must be included in the height calculation, however structures such as receiving antennae, chimneys or flues are not included.

What is a storey?

A storey is the part of a building between floor levels.

If there is no floor above, it is the part between the floor level and ceiling. It may include an attic, basement, built over car parking area and mezzanine.

What is natural ground level?

Natural ground level is the natural level of the site before any excavation or filling (in the past or as a part of any proposed development) has been carried out on the site.

A storey is considered to be above natural ground level when any part of it projects more than 1.2 metres above natural ground level.

Further information & diagrams

The Department of Environment, Land, Water and Planning has a publication on building heights which can be viewed for further information.

This publication includes diagrams on measuring building heights and storeys, including where the land is sloping
