The Builders Standing Up to a Broken Industry

““On paper, six or seven different business owners trying to run one organisation together makes no sense.”

We sat down with Bec Kempster, the COO of the Sustainable Builders Alliance (SBA), to talk about what it actually takes to scale an industry movement, structure chaos into strategy, and make a difference in the building industry.

Bec has what you’d call a "coloured career". From studying economics at university only to realise market theories completely ignore irrational human behaviour, to managing marketing for legendary Melbourne nightclubs and coaching architects on how to actually run profitable businesses. But 18 months ago, she stepped into the SBA. What she found was an alliance of six passionate directors throwing out millions of great ideas, but desperately needing a professional framework to turn those ideas into an industry shift.

Structuring the Chaos: Scaling Beyond the Bubble

When you’re a custom builder or a passionate designer, it’s easy to live in a comfortable bubble. You look at your Instagram feed and think everyone is on board with high performance. But the grim reality is different.

The SBA originally spun out of Builders Declare; a great movement and an important cause, but a cause isn’t a structural tool. To scale, the SBA had to step up and become a legitimate, professional association. On paper, having half a dozen competitive builders making collective decisions is a nightmare. The game-changer under Bec’s leadership was splitting the operation into distinct corporate departments, turning a chaotic room of ideas into a logical, scalable machine.

It requires humility. As builders, we are used to being the absolute masters of our own destiny on site. But to drive real change across an industry, you have to learn to check your ego at the door, voice your piece, and back the collective vision.

The Theory of Change: Owning the Definitions

There is a massive, frustrating gap in the Australian market right now regarding what a "high-performance" or "net-zero" home actually means. Right now, anyone can slap some wrap on a frame, put in a ventilated cavity, and scream from the rooftops about their high-performance renovation. But you're just building to basic Victorian code at that point.

The SBA’s ultimate, lofty goal is to make genuine, net-zero sustainable homes completely mainstream. To the point where the organisation makes itself entirely redundant in 20 years. To get there, Bec and director Jeremy Spencer have been mapping out what they call the Theory of Change, anchored by five major pillars:

  1. Practical Industry Guidance: Evolving a real, site-level roadmap based on what builders are actually executing on the ground, not purely academic theories.

  2. Developing Education: Co-developing localised, practical courses directly with TAFEs like Melbourne Polytechnic so the next generation enters the workforce pre-educated.

  3. Building Workforce Capacity: Giving homeowners a clear, badged register to find verified, competent professionals.

  4. Strengthening Industry Alignment: Uniting separate industry bodies. From Renew and the Passive House Association right through to the HIA and Master Builders, to read from the same handbook.

  5. Championing the Mission: Correcting deep-seated industry misconceptions and advocating for structural change at every tier.

The State of the Market

SBA recently ran a data-driven survey tracking over 140 residential builders across Australia, and the findings exposed a massive market blind spot. The data split the sector into three distinct groups: high-performance builders, standard builders, and a massive pocket of transitioning builders.

Transitioning builders are already building above code. They know how to do the work and they want to do it right, but they are dropping the ball on one massive front: marketing and sales. They aren't actively articulating comfort, health, and running costs to their clients. Because they stay silent, they get trapped dealing with clients who have zero understanding of real building costs.

Meanwhile, the data proved that the builders who openly position themselves as high-performance experts are nearly twice as likely to have their pipelines locked in more than six months ahead compared to the rest of the market. 

The consumer appetite is already there. The cost crisis is a global issue, not a performance issue—building is inherently expensive whether you build a rotting, drafty box or a healthy, durable home. If you are a builder trying to break into this space, you have an incredible opportunity to get in front of the camera, be vulnerable, and document your learning curve. Clients respect a builder investing heavily in their own education because it means that builder is far less likely to become an insolvency statistic.

Evolve or Get Left Behind

We cannot continue to tip-toe around the reality of the Australian construction landscape. Building is complex and running an owner-dependent business while trying to guess your way through sustainability targets is a recipe for burnout. 

True innovation isn’t about chasing aesthetic awards or hiding behind basic compliance paths; it’s about pulling your head out of the sand and upskilling your business for the future. By joining a unified network like the SBA, getting listed on the Sustainable Building Directory, and committing to verified site standards, you stop guessing and start future-proofing your business. The industry is shifting beneath your feet. You can choose to be a transitioning builder stuck in the silent middle, or you can step up, claim your authority, and lead the charge.
