This thoughtful extension of a modest weatherboard house, situated on a quiet suburban street, seamlessly integrates sustainability into every aspect of its design and construction, from initial concept through to end-of-life considerations. The project is rooted in a commitment to reducing the home’s embodied and operational energy, as well as its social and biodiversity impacts. Central to this approach is a compact footprint that maintains below-average site coverage, guided by passive solar design principles to optimize solar access, thermal comfort, light, and ventilation.

The design employs several passive solar strategies to enhance the home’s overall amenity and environmental performance. A southwest-facing pond cools air during the summer, while a winter garden extends the lounge area and functions as a thermal buffer, enhancing indoor comfort. A netted void over the dining space acts as a thermal chimney, helping to pre-heat the upstairs in winter and venting hot air in summer. Internal windows ensure natural light penetrates deep into the house while enabling effective cross-ventilation, and an external timber frame provides essential shading and light filtration. Additionally, elevated planters near the windows serve dual purposes as edible gardens and as a means to reduce radiant heat during the warmer months.

Overall, this project represents a balanced approach to sustainable living, where environmental responsibility, social engagement, and aesthetic appeal converge to create a home that is as thoughtful as it is beautiful.
