Parnell Avenue House in Sorrento, Western Australia, is a thoughtfully designed, energy-efficient home on a compact 353m² infill lot. Designed for a family with a modest budget, the 175.6m² home includes three bedrooms, two bathrooms, and a garage/workshop. Prioritising flexibility, sustainability, and strong indoor-outdoor connections, the design features two offset rectangular volumes, creating a south-facing terrace and a north-facing courtyard.
With a smaller-than-average footprint, the home reduces costs and environmental impact while maximising garden space for outdoor living. Passive design principles such as optimal orientation, cross-ventilation, thermal mass, and shading ensure year-round comfort, complemented by active energy systems like rooftop solar with battery storage and rainwater collection. The material palette, inspired by 1960s Western Australian modernist homes, blends white-painted brick with breezeblock screens.
Parnell Avenue House exemplifies how a well-considered design can achieve a functional, adaptable, and sustainable home that balances affordability with high-quality living.
We love our house and the lifestyle it gives us, it feels like it’s tailor made for our needs. It affords a secure, calm and private feel without being entirely cut off from the street. It’s both cozy in winter and surprisingly able to handle the heat of summer with a need to run the a/c occasionally. We spend most of our time in the spacious living area which feels larger than it is because of the connection with the outdoors. It’s been a joy to watch the birds and garden grow around us.
