“The difference between a good businessman and a bad businessman is the good one fails and learns.”

Andrew Hopkins (Hoppo from Hopkins Construction) is the tradie story a lot of people live through, but don’t post about. Early wins. Dumb money. Bad advice. A business that looks fine from the outside. Then the crash. Then the rebuild.

We sit down with Tom from Vision 2 Estimating (V2E) to talk about why traditional construction estimating and 2D-only take-offs are costing builders real money. If you’re quoting off PDFs, squinting at elevations, and hoping the details sort themselves out on site, this conversation will hit. It’s about accurate building estimates, protecting margin, and pricing work properly in modern Australian residential construction.

Let’s stop tip-toeing around the reality of the Australian housing market. We are throwing up volume-built boxes and high-density apartments that are practically end-of-life before they’ve even seen their first winter. We sat down with Linden Thorley, architect, Passive House designer, and chair of the Australian Passive House Association Retrofit Committee.

“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.

“Money turns to water.” In this episode, we sit down with Dave from Pro Clima (Technical Innovation Engineer) to talk about the real transition from being on the tools to quoting jobs, running projects, and trying to keep cash flow under control.

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.

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.

“I don’t understand why people build houses like this.” 

We have both said some version of that on-site, usually after seeing a detail that was always going to fail. A leaky junction. A sweaty wall. A home that is freezing in winter and cooking in summer. Not because the builder was evil, but because the industry has normalised shortcuts and shrugged-off consequences for so long that bad outcomes start to feel inevitable.

“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.

“Version one is better than version none.”

James Brown means it in the most practical way possible for builders. A rough first system in your building business is better than no system at all. Not the perfect process. Not the spreadsheet you will build “when things slow down”. Just something written down that gets the ball rolling, so you can test it, hand it to someone else, and improve it over time.

“Legally, you can still build a house with no membrane.” 

That was Villy Yordanov, Pro Clima’s Innovation Engineer, saying the quiet part out loud. Villy knows his stuff, too. He has a Bachelor of Mechanical Engineering from VIA University College in Horsens, Denmark, and a Master of Mechanical Engineering from UTS in Sydney.

Some episodes remind you why you started a podcast in the first place.

We sat down with Erik, a German journeyman carpenter, and within about five minutes, we were already thinking, hang on… have we made life way more complicated than it needs to be? Because Erik is living inside a tradition that feels almost impossible in 2026: travelling for three years and one day, working wherever he can, learning from other tradespeople, and doing it without a mobile phone.

We sit down with Helen from Renew to unpack why the idea of a sustainable home still gets treated like a luxury, when it should really be the baseline. We talk about the shift happening across the Australian building industry, where sustainable housing, energy efficient homes, and high-performance building are becoming more mainstream. Better design decisions, not just bigger budgets, can lead to healthier, more comfortable, and more resilient homes.

The industry is shifting. Fast. Economically, technologically, emotionally... and if you are a builder or business owner, you are probably feeling that in one way or another.

The building industry has been under pressure, and for a lot of people, it feels uncertain. One of the things we spoke about was how quickly things can change, even outside the usual construction challenges.
