Building Height Explained

Clause 4.3 of the Local Environment Plan (LEP) deals with building height, but clause 4.3 may also be subject to certain exceptions under other provisions of the Local Environment Plan (LEP).

The Height of Building (HOB) dataset describes the maximum building height allowed for areas.

Building Height is defined as the vertical distance between ground level (existing) and the highest point of the building, including plant and lift overruns, but excluding communication devices, antennae, satellite dishes, masts, flagpoles, chimneys, flues, and the like.

The height of a building is measured from the existing ground level, which is the ground level of a site at any point before any earthworks (excavation or fill) have taken place, as illustrated in the below figures.

For example, an 8.5m height limit is the maximum vertical distance between ground level (existing) and the highest point of a new building, typically the ridge line of the roof.
