Building a sustainable home is more than just a trend; it is an investment in the future. With increasing environmental concerns and rising energy costs, a sustainable dream home is becoming a necessity rather than a ‘nice to have’. But where do you start? In this comprehensive guide, we’ll take you through the process of planning your sustainable dream home in Perth, Australia. From choosing between a passive house and passive solar design to incorporating recycled materials and creating a water-wise garden, we’ve got you covered.
Passive House, Passive Solar Design or a custom home?
When it comes to sustainable home design, two popular options are the passive house and passive solar design. The passive house (Passiv Haus) is a building standard focusing on energy efficiency by using superior building envelope insulation and making the house airtight. It aims to create a home that requires little to no heating or cooling, resulting in lower energy bills and a smaller carbon footprint.
The passive solar design uses the sun’s position and prevailing winds for ventilation to regulate a home’s temperature throughout the year, allowing for warmth in winter and coolness in summer through strategic placement of windows, shading, and thermal mass. This approach considers the need for active ventilation to cool the home down. Assessing your needs and goals is important to determine which approach works best for you.
A custom home has a minimum energy efficiency rating of 6 in Perth, Australia. However, with good design and construction methods this rating can easily be boosted to ~8 Star NatHers rating. We call it a hybrid, better performing home.
Choosing Sustainable Building Materials
Choosing the right building materials can significantly impact your dream home’s sustainability. Recycled building materials, such as reclaimed brick and recycled concrete, are great options, as they reduce the amount of waste in landfills and require less energy to produce than new materials. More sustainable materials, such as timber harvested from professionally managed forests, are also a good choice. It’s important to consider the lifecycle of the materials, including their production, transportation, use, and disposal when selecting.
The Importance of Proper Insulation
Proper insulation is crucial for creating a sustainable dream home. It helps regulate indoor temperatures, reducing the need for heating and cooling systems and minimising energy usage. Thermal insulation should be installed in external walls and ceilings, and it’s important to choose materials with a high R-value, which measures the material’s resistance to heat flow.
Energy-Efficient Appliances and Lighting
Incorporating energy-efficient appliances and lighting can significantly reduce your energy consumption and save you money on your energy bills. Look for appliances with the ENERGY STAR label, designed to use less energy and reduce greenhouse gas emissions. LED lighting is also a great choice, as it uses less energy and lasts longer than traditional incandescent bulbs. We also advise homeowners to use a heat pump for warm water and electric cooking. These are highly efficient devices, and it helps you avoid a gas connection to your home, further reducing your carbon footprint.
A Water-Wise Garden
A sustainable dream home extends beyond the four walls of the house. A water-wise garden can help reduce water usage and create a beautiful, low-maintenance outdoor space. Native plants that are adapted to the local climate are a great choice, as they require less water and are more resistant to pests and diseases. Incorporating drip irrigation systems can also help reduce water usage and ensure your garden stays healthy and vibrant.

Building a sustainable custom new home in Perth, Australia is a worthwhile investment for the environment and your wallet. By choosing between a passive house and passive solar design, selecting sustainable building materials, creating a water-wise garden, incorporating energy-efficient appliances and lighting, and ensuring proper insulation, you can create an environmentally friendly and comfortable home.
