How we calculate construction costs

The construction cost information above is provided as a general guide to allow you to estimate the potential construction costs for a building type. Our costing information is based on assumptions concerning construction type, quality and condition of inclusions. Costs provided are an average price for typical buildings as at the date of publication, allowing for preliminaries, builders profit and overheads. Costs can provide no more than a rough guide to the probable cost of building, as costs vary significantly based on site conditions, level of fitout and design.

Two of the main considerations used in the above calculations are the Gross Floor Area (GFA) rate and pricing adjustments for the regional variations.

Gross Floor Area calculation

Typically GFA can be defined as the sum of the fully enclosed covered floor area and the unenclosed covered floor area of a building at all floor levels, measured in a square metre rate. GFA consists of two elements:

FECA
FECA | Fully Enclosed Covered Area
See examples >
  • Basements
  • Attics
  • Garages
  • Penthouses
  • Lift shafts
  • Staircases
  • Columns and piers
UCA
UCA | Unenclosed Covered Area
See examples >
  • Roofed balconies
  • Open varandahs
  • Porches and porticos
  • Attached covered walkways
  • Usable space under buildings
Regional Variations

Regional variations consider the pricing differences for each region and are used to provide a more comprehensive range of construction costs. This table multiplies the default regional value Sydney, by the appropriate regional percentage to find the approximate cost for the construction type per square metre in the selected area.

The percentage variations are below:

Cairns
110% - 130%
Brisbane
95% - 115%
Sydney
100% - 100%
Canberra
92% - 120%
Melbourne
95% - 105%
Hobart
95% - 120%
Adelaide
95% - 108%
Perth
98% - 120%
Darwin
110% - 135%
