Average Cost to Build a 4 Bedroom House in Australia.

The great Australian dream lives on, and many of us strive to own our own home. With savings on stamp duty, building a house may be more appealing when compared with buying an established home. Either way, it’s important to do your research to see what suits you best.

You’ve decided you want to build a house, but how much will it cost? Here are some points to consider when trying to work out the cost of building a 4 bedroom home in Australia


How big is the house likely to be? Closer to 195 square metres, or more like 390 square metres? Think about the size of your rooms. For example, whilst there is no minimum size requirement for bedrooms, many people say to opt for a minimum of 3.5 metres x 3.5 metres for the master bedroom, with other bedrooms sized around 3 metres x 3 metres. Approximate building costs in Australia currently sit around $1,680 per square metre for a budget build, or, $3,550 per square metre for a high-end build.

This is perhaps where the biggest variables in cost can occur. Is your block of land flat and level? Sloping blocks often mean higher site costs. They often need a more rigorous site survey. The survey will determine the drainage, soil stability, wind exposure and structural design of the house to suit the slope of the land. More excavation work is usually required for sloping blocks. A cut and fill process will create a level platform for the foundations or concrete slab.

3. Energy Rating requirements

All new homes or renovations in Australia must meet a six-star energy rating. This indicates a good, but not outstanding, thermal performance. The higher the energy rating, the more energy efficient your house will be. Achieving a higher energy rating at the start may be more expensive, but think about the long term savings on your energy bills! Glazing is one way to increase energy efficiency. Window tinting with solar film will also help you save on energy bills, and increase privacy.
