Sustainable & Energy Efficient Homes in Perth metro
Building a home that costs less to run in Perth
A sustainable build in Perth starts with the block. Good builders orient living areas to the north, size eaves for summer shade and winter sun, and cut west-facing glass that bakes in the afternoon. Then come insulation, double glazing, sealed construction, efficient hot water (heat pump or solar), and rooftop solar with space for a battery. Some builders also work to Passive House or similar standards.
When comparing the 13 builders listed here, ask for the energy rating on past homes, not just a brochure claim. Check what is standard and what is an upgrade, and ask to see a home that is at least a year old. Confirm who does the thermal modelling and whether the builder will show you the result before you sign.

Common questions about sustainable & energy efficient homes
- How much more does an energy efficient home cost to build in Perth?
- Expect roughly 3% to 10% more than a standard build for better glazing, insulation, solar and design changes. Full Passive House builds can cost more. Many upgrades pay back through lower power bills, but the timeline depends on your usage and the features you choose.
- What energy rating should I aim for?
- New homes in Western Australia must meet the National Construction Code energy requirement, currently around 7 stars. Going higher, such as 7.5 to 8 stars or beyond, gives extra comfort and lower running costs. Ask for the actual rating report for your design.
- What should I expect during the process?
- The builder should model your design against the block orientation, then adjust window sizes, shading and materials. Expect a few extra weeks in design, and checks on insulation and airtightness during construction.
- How do I judge quality in a sustainable builder?
- Ask for completed homes you can visit, rating certificates, and a clear list of inclusions. Be wary of vague claims like 'eco friendly' without numbers. Check references from owners who have lived through a Perth summer in the home.
