Custom Home (6-star rating)

The standard home for home building with builders in Perth is a 6-star energy-rated home (NAThers). This is the minimum requirement in Perth. Compared to older homes designed and built without energy efficiency in mind, this custom home offers a comfortable living environment. With double brick walls and ceiling insulation, it ensures reasonable energy efficiency. The new home builder who wants to build in Perth, can get started with a budget of around $420K, or $2,100 per sqm.

Custom Energy-Efficient Home (7+ star rating)

The custom energy-efficient home, features superior insulation and thermal control. With double brick walls, high-quality glazing, and a heat pump or solar-powered hot water system, it’s a good start to a comfortable, energy-efficient home. If you care about building a quality, comfortable home, reducing energy bills and minimising your impact on the environment, it starts around ~ $460K for a 200 sqm home, or $2,300 per sqm.

Passive Solar Homes (8+ star rating)

Enjoy maximum energy savings all year round with a passive solar home in Perth. Boasting an 8+ star rating, potentially up to a 10-star energy-efficiency rating (NAThers), this innovative residence utilises high-quality insulation and glazing. With improved insulation values in the walls, roof and ceilings, overall costs are higher yet worth it for maximising energy efficiency, reducing energy bills and enjoying a comfortable indoor climate year-round. An elegant exposed concrete slab provides thermal mass to maximise these benefits further. Shading in the building’s home design protects against direct sunlight in the warmer months to avoid solar heat gain in the home. A passive solar home with an 8+ star rating starts at ~ $540K for a 200 sqm house or $2,700 per sqm. This option is perfect for those looking to embrace solar passive home designs.

Passive House

Passive Houses are constructed to stringent standards that limit air changes per hour (ACH) to less than 0.6 (in comparison to NatHERS, which assumes ~ 12 air changes per hour). Despite not being eligible for the highest NatHERS ratings due to different parameters used in the rating of heating & cooling demands, these homes still guarantee outstanding thermal comfort and exceptional performance. So you can have peace of mind while enjoying a wonderful indoor climate and a reduced carbon footprint.

Based explicitly on the Passiv House principles, Passive Houses include superior insulation to external walls, ceilings, and roofs. They are built with timber framed, double batten walls with an airtightness membrane to the inside and a vapour barrier to the outer side. Without ‘natural’ ventilation, Passive Houses have an HRV system for mechanical ventilation throughout the house, providing fresh air everywhere. The window frames, doors, and doors are all of the superior quality in terms of insulation and air-tightness. Shading devices are required to block the sun in summer.

A Passive House (Passiv House) starts at ~ $3,900 per sqm, totalling ~ $780K for a 200 sqm home.

Sustainable Homes by Builders in Perth

For those looking to build sustainable new homes, the aspiring new home builders in Perth can include energy-efficient home designs, rainwater harvesting, recycled and recyclable materials, adding a conservative $30K to the building cost of a custom energy-efficient home, a passive solar home or a passive house.

One aspect of sustainable homes is that they need to be energy-efficient and reduce energy consumption where possible. A custom, energy-efficient home of at least 8 stars would be the minimum.

Other features to be considered when building an eco home are water-efficient toilets, taps and shower heads and a grey water system, allowing you to recycle water in the garden. A sustainable garden should also be Waterwise, containing plants and trees native to Perth and Western Australia. 

Building Variations and Land Considerations

Building a smaller home or a two-story home affects the total cost. Another aspect that will increase cost is building blocks with significant variance in ground levels. While such building blocks can often be utilised to build beautiful homes with massive appeal, it does make building more difficult and impact home designs and construction complexity.

  • Smaller or two-story homes, luxury finishes, and sloped building blocks can influence the total cost.
  • Non-rectangular designs and high-end finishings also impact the final price.
  • Elevated land in Perth may incur additional costs due to earthworks and retaining requirements.

Home Designs and Impact on Costs

What you will likely encounter designing and building your dream home, is that most home designs are not completely rectangular. When creating your home designs, you will often end up adding style elements to both the exterior as well as the interior of your home designs. This helps you optimise the space, features, and flow and use of your new home.

The last aspect that dramatically impacts overall building costs is getting higher-end finishings, high-spec appliances, and bathrooms with a custom home builder. And any addition to the house, like a swimming pool, sauna, or spa, will also lead to higher investment with builders in Perth.

Conclusion

Building a custom home in Perth involves various considerations, from passive solar homes to custom energy-efficient home design, choosing the right home builder is essential.
