Australia's leading voice for Net Zero Sustainable Homes.

We're working to make net zero sustainable homes the standard, not the exception. As a social enterprise, we bring together builders, architects and industry professionals committed to building better.

Why it matters

The problem with our homes

The homes we build today shape how Australians live for decades to come. They affect our energy bills, comfort, health, resilience to extreme weather, and the environmental footprint we leave behind. Yet many homes continue to underperform in ways that cost both people and the planet. We already have the know-how and technology to fix it — what's missing is widespread adoption.

Health

Australian homes are making people sick.

  • Gas cooking is linked to up to 12% of childhood asthma in Australia
  • A global meta-analysis links gas cooking to a 42% increase in asthma risk
  • Toxins, mould and VOCs contribute to Sick Building Syndrome
Quality

Most new homes are built to a substandard thermal quality.

  • Homes are expensive to heat and cool, impacting comfort and health
  • Climate resilience is compromised by poor sealing and ventilation
  • Poor quality builds compound both carbon and health impacts
Carbon

Buildings are responsible for 39% of global carbon emissions.

  • The average Australian home emits 5t CO₂ per year in operation
  • Embodied carbon exceeds 1t per m² — the dominant source for new homes by 2050
  • The industry must align with Australia's Paris Agreement commitments
Resources

Buildings consume 50% of global resources.

  • Deforestation driven by over-reliance on forest timber in construction
  • Global biodiversity has declined 69% in just 50 years
  • Construction and demolition waste makes up 39% of landfill
  • Australia's circularity rate is ~4% — half the EU average
Our Mission

To make construction of Net Zero Sustainable Homes mainstream.

We want these homes to be widely adopted, accessible and affordable to all. They should be considered the standard by builders, buyers, regulators and communities alike.

'Sustainable' is one of the most overused words in construction. For us, it means something specific. A truly sustainable home goes beyond energy performance. It considers the materials used to build it, the health of the people who live in it, its resilience to a changing climate, and its impact on the natural world.

When we talk about sustainable homes, we mean homes that genuinely address:
Low impact materials
Water conservation
Circularity
Healthy indoor environment
Thermal comfort
Climate resilience
Nature positive

Our Story

Born from a conversation,
built on conviction.

The Sustainable Builders Alliance began with a simple question from Australian Architects Declare back in 2020: could builders come together to create their own movement for change? We put the call out for builders who genuinely cared about building better and protecting the future for the next generation. A handful answered. After a couple of beers and plenty of honest conversation, Builders Declare Australia was born — with no grand masterplan, just a shared belief that the construction industry could and should do better.

Over the following years, through lockdowns, industry uncertainty and countless meetings, the founding group worked to transform passion into practical impact. As builders ourselves, we knew good intentions alone would not cut it. The industry needed real outcomes, not empty promises. That process led to the creation of the Sustainable Builders Alliance — a community focused on giving builders and other industry professionals the knowledge, tools and support to deliver more sustainable, high-performing homes and help drive meaningful change across the industry.
