•
Areas are measures in two dimensions and should be expressed in square 
metres (m
2
);
•
Larger areas, rural properties and older buildings commonly have irregular 
shapes. Care should be taken to measure such areas accurately, perhaps by a 
land survey, or the use of digital maps. The areas can be expressed in hectares;
•
Volumes are measures in three dimensions and should be expressed in cubic 
metres (m
3
).
3.1.4. 
Distance
•
Gross length is measured as the horizontal distance between either the outer 
faces of exterior walls or between the centres of interior walls. The choice of 
basis should be stated;
•
Net length is measured as the horizontal distance between the inner faces of 
exterior walls, disregarding internal structural components such as pillars or 
buttresses that are not complete walls;
•
Gross height is measured as the vertical distance between the top of a finished 
floor and:
•
The top of the finished floor of a room situated above it; or
•
The top of the roof structure above it.
•
Net height is measured as the vertical distance between the top of a finished 
floor and the bottom of a ceiling, floor or roof situated above it, disregarding 
internal structural components that are not complete ceilings;
•
Free height is measured as the vertical distance between the top of a finished 
floor and the underside of a suspended ceiling above it.

•
Net areas are determined by using net lengths;
•
Gross volumes are determined by using gross lengths;
•
Net volumes are determined by using net lengths.
