A Passive House is a high-performance, energy-efficient home designed to maintain comfortable indoor temperatures year-round with minimal energy use. It uses features like super-insulation, airtight construction, and advanced ventilation systems to drastically reduce heating and cooling needs and provide premium air quality. Learn more here.

At ThermoBuild, we specialise in Passive House construction and sustainable building practices. We go above and beyond Australia’s National Construction Code to deliver homes that are not only beautiful but also low-energy, low-impact, and built to last.

We’re based in Winchelsea, Victoria, and serve clients throughout the Surf Coast, Geelong, the Otways, and broader Southwest Victoria.

We offer both! In addition to new Passive House builds, we specialise in retrofitting and renovating existing homes to improve energy efficiency and sustainability.

Costs vary depending on design, size, and materials, but Passive Houses often result in long-term savings due to dramatically reduced energy bills. We’ll work with you to create a solution that fits your budget and goals.
