High Performance Homes and Passivhaus in Margaret River
Energy-efficient homes designed for comfort, health and longevity.
In an era of rising energy costs, extreme weather and increasing environmental awareness, the way we build homes matters more than ever. More Australians are now choosing high performance homes and Passive House (Passivhaus) design as a smarter, healthier and more sustainable way to build.
At Two Hammers Construction, we specialise in high performance home builds and major renovations across Margaret River and the South West — creating homes that perform exceptionally well in our local climate, without compromising on craftsmanship or design.
What Is a High Performance Home?
A high performance home is designed and built to exceed standard building codes.
It focuses on:
Energy efficiency
Thermal comfort
Airtight construction
Indoor air quality
Long-term durability
Every element — from insulation and glazing to ventilation and detailing — is carefully considered to reduce energy demand and improve how the home feels to live in.
The result? A home that stays cooler in summer, warmer in winter, and more comfortable year-round — with significantly reduced reliance on heating and cooling systems.
What Is Passive House (Passivhaus) Design?
Passive House (Passivhaus) is the world’s leading standard for energy-efficient building.
Originally developed in Germany, Passive House uses proven building science to dramatically reduce the energy required to heat and cool a home — while delivering outstanding comfort and air quality.
A Passive House–designed home typically includes:
High levels of continuous insulation
Exceptional airtightness
Thermally broken, high-performance windows
Mechanical Ventilation with Heat Recovery (MVHR)
Thermal bridge-free detailing
Rigorous planning, testing and quality control
When designed and built correctly, Passive House homes can use up to 90% less heating and cooling energy than a standard new build.
Benefits of High Performance & Passive House Homes
Year-Round Thermal Comfort
No drafts, cold spots or overheating. High performance homes maintain stable internal temperatures in all seasons — quietly and efficiently.
Lower Energy Bills
Reduced heating and cooling demand means significantly lower ongoing energy costs.
Healthier Indoor Air Quality
Continuous mechanical ventilation supplies fresh, filtered air while removing moisture and pollutants — reducing mould, condensation and allergens.
Sustainable & Future-Ready
Energy-efficient homes lower your carbon footprint and protect against rising energy prices and future climate extremes.
Built for Longevity
Better detailing, smarter material selection and airtight construction lead to improved durability and fewer maintenance issues over time.
