Mindful Builder

In this episode, we sit down with Jackson from Enduro Builders in Adelaide to talk high performance homes, energy efficient construction, and what it actually takes to build houses that perform year after year. We recorded inside a Passive House, and once you feel that level of comfort and stability, it’s hard to accept what “normal” housing has been getting away with.
Jackson has been building certified Passive Houses and energy efficient homes in South Australia for more than a decade, and he keeps it simple. No magic. No secret sauce. Just good design, tight detailing, and refusing to cut corners where it counts. We take a look at what makes a home feel consistently warm (or cool), how the building envelope does the heavy lifting, and why comfort is a measurable outcome, not a marketing line.
One of the best parts of this chat is how practical Jackson is about targets. Not every project needs certification, and not every client wants the same thing. We talk Passive House principles, performance tiers, and how to choose the right materials and systems for the brief, the budget, and the climate. The point is not the badge. The point is building performance, durability, and homes people can actually afford to live in.
We also get into the real-world negotiations builders face: design vs function, heating choices (including hydronic heating and wood fires), and what “cosy” really means in a well-built home. Plus, Jackson shares why he’s using Cross Laminated Timber (CLT) in his own build, and why systems and processes are the backbone of a sustainable building business. If you’re a builder, architect, designer, or homeowner who cares about sustainable construction in Australia, this episode will shift how you think about good building.

“Do we want 1.2 million crappy houses?” That’s the question Jesse Clark (pro clima) drops early in this episode, and it pretty much sets the tone. We talk about Australian housing supply, building quality, and why “more homes” is not the win if we’re locking in mould risk, discomfort, and expensive fixes for decades. If you care about better homes, healthier homes, and what the future of construction should actually look like, this one’s for you.
Jesse’s whole approach is simple and repeatable building systems. We look at practical building science for real sites: the building envelope, airtightness, membranes, wraps, and the kind of construction details that can be done consistently across projects without relying on luck or one superstar tradie.
A big focus is moisture management and ventilation, because moisture safety is the foundation of durable homes. We get into vapour-permeable assemblies, how leaky buildings happen, and why mould in Australian homes is often the outcome of small decisions made early. We also touch on the debate around energy efficiency and building codes (NCC), and how chasing energy targets without understanding moisture can create unintended consequences.
If you’re a builder, architect, designer, certifier, or homeowner trying to understand high performance homes without the hype, this conversation will help. Topics include sustainable building, passive house principles, condensation control, indoor air quality, and what it takes to build homes that last in Australian climate zones.

We do not usually have politicians on the show, so sitting down with David Southwick, the Planning, Building, and Construction Minister for the Liberal Party’s Shadow government, made for a very different kind of conversation. Less product talk and site detail, more housing policy, building regulation, and the decisions that shape what builders can actually do on the ground. If you work in the construction industry in Australia, this episode is a useful look at the levers that affect your day to day.
David’s path into politics is not the usual script. He has been a DJ, a businessman, and a small business owner, and that comes through in how he talks about the industry. A big theme is the need for governments to listen to builders, tradies, and industry experts, not just write rules from a distance. It is a practical conversation about decision-making, consequences, and what happens when policy does not match reality on site.
We get into the messy part of the current housing market. Construction costs, interest rates, red tape, delays, and the pressure to increase housing supply fast. But we are not interested in building more homes if they are worse homes. We talk about affordability alongside build quality, comfort, durability, and the long-term cost of homes that underperform. This is where topics like tax, approvals, and compliance start to matter just as much as what happens on site.
We also explore future-focused solutions like prefab housing, kit homes, and 3D printing in construction, plus the need for stronger trade education and longer apprenticeships to lift capability across the industry. The thread running through it all is confidence and certainty. Builders need stable settings to invest, hire, and train, and clients need confidence to commit. Whether you agree with David politically or not, this is a grounded builder reality check on how politics and construction intersect, and what needs to change to support better outcomes in Australian housing.

“I don’t understand why people build houses like this.” If you have ever said that on site after spotting a leaky junction, a sweaty wall, or a home that is freezing in winter and cooking in summer, you are not alone. This conversation is our pushback against the shortcuts that have become normal in the Australian building industry. The whole point of More Good and Less Bad is simple. Build better homes, make fewer mistakes, and deliver healthier, more comfortable results through better building performance and smarter decisions.
We recorded this one at Pro Clima HQ in Sydney with Andy Marlow, director at Envirotecture and a certified Passive House designer. Andy has a rare ability to talk about sustainable building without the greenwashing and without making it feel like a lecture. The focus is on outcomes that matter to homeowners and builders alike. Homes that perform, homes that last, and homes that do not quietly fail behind the plaster.
We also dig into the Living Building Challenge, because it is one of the few sustainability frameworks that does not let you cherry-pick the easy bits. It looks at the full picture of holistic sustainability in construction, including materials, energy, water, and health. Not because every project needs a badge, but because it forces better questions about what sustainable construction really means when you zoom out and look at long-term impact.
Finally, we talk about making Passive House principles more buildable and accessible through Andy’s Passive House Design and Construct model. Pre-designed, high-performance homes that still leave room for personal choice, without reinventing the wheel every time. We also share the lessons we have learned the hard way, and why building with intention is about mindset, systems, and balancing the ideal with what is financially feasible and genuinely buildable on real sites.

“As builders, you have huge overheads. Massive.” Matt said it mid-conversation and it just sat there, because it is the part people outside the construction industry rarely see. They see the finished home and the invoice. They do not see the cash flow pressure, the holding costs, the insurances, the compliance, the admin load, the delays, and how quickly one wobble in the pipeline can hit a building business. That is where this chat with Jessica Kismet from Climasure, host of the Building Sciology Podcast, really goes.
Jessica jumps in as guest host and asks the questions builders usually keep to themselves. Money pressure. Risk. Ego. Family. The emotional load of running a residential construction business in Australia, especially when the market is tight and the margin for error is small. If you are a builder, contractor, or tradie trying to stay steady through uncertainty, this episode will feel very familiar.
We talk openly about the financial tightrope and what it means to actually know your numbers. Builder margins, overheads, pricing, and the real cost of delays are not optional knowledge anymore. Post-COVID, “she’ll be right” is not a strategy. This conversation gets into the learning curve, the mistakes, and the shift from running on instinct to running a more sustainable construction business that can last.
We also get into bigger industry questions. Would we encourage our kids to become builders? Who is the real villain in the building industry, from legislation to contracts to banks and insurance? How do you set boundaries with clients, protect your process, and avoid the compromises that come back to bite you later? And we finish on the long game of building science, where better outcomes depend on builders, architects, and designers understanding the whole system, not just their part of it.
