You're in the early planning stages of your building project and just want a ballpark estimate of what your building costs are going to be. This can be a very difficult exercise or relatively easy. Either way, you need to make sure you understand what the cost of building a house includes.
The easiest way to calculate building costs is to use figures supplied by your local council. In most cases, the estimates will be divided into low or project home prices; medium or standard finish; and high standard finish. An example of a regional New South Wales standard finish home might look like this:
The price difference can be significant between the standards chosen. In the same area, a "project" brick veneer home would be about $1000m2 while a "high standard finish" brick veneer house is estimated at $2250m2.
To arrive at an estimate of your building costs, all you have to do is calculate the size in square metres of your house and multiply it by the estimate provided by your local council.

As a rule, cost estimates provided by council will include all the building costs, including council fees, materials, labour and building inspections. They do not include the cost of a drafter, an architect or structural engineer. The square metre costs provided will be an average cost based on the costs of hundreds of houses. One "standard" timber frame house might have cost only $1100m2 while another may have cost $1800m2, with the "average" being $1450. When you multiply the number of square metres you need by those square metre rates, the difference is significant, so add or subtract from the average depending on your inclusions.
The easiest and most accurate way of calculating building costs is to let the professionals do it for you.
