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.

“Technology is not coming for construction. It’s already here.” 

That was the feeling running through our conversation with Vas from C.R. Kennedy, and honestly, it is hard not to get excited about where things are heading. Because this is not just about shiny gadgets or sci-fi site toys. It is about tools that make building more accurate, more efficient, safer, and a whole lot easier to communicate to clients.

“Sustainable design is not just lower energy bills. It is health, comfort, moisture safety, and long-term performance.” 

That was the thread running through our conversation with Marcus Strang from HIP V. HYPE. Marcus is the Technical Lead in Passivhaus at HIP V. HYPE, with a PhD from the University of Queensland and a seriously deep understanding of what makes buildings work, or fail, over time.

“Sustainable buildings focus on what's invisible, not visible” 

That was one of the clearest ways Roberto Petruzzi summed up what Environmentally Sustainable Design (ESD) actually is. Not a buzzword. Not a compliance badge. A set of decisions that shape comfort, durability, and real-world building performance.

“Commercial teaches you speed and logistics. Residential teaches you people.” 

In this episode, we sit down with Alistair Meallin, Director at Y Projects, to talk about what it really takes to build high-quality custom homes in Australia. With over a decade in construction and a construction degree from the University of Melbourne, Alistair shares the lessons he learned on big commercial sites and why he ultimately moved into residential building for the client connection.

“Architecture is not just drawings and pretty renders.” In this episode, we sit down with Roger from Borland Architecture to unpack the overlap between architecture, construction, and real estate, and why those worlds are far more connected than most people realise. This is a practical conversation about problem-solving, designing for real life, and making decisions that affect how people live every day.

“Success looks great on social media. The reality is usually messier.” 

In this episode, we sit down with Liam Wallis, Founder and Managing Director of HIP V. HYPE, to talk about what sustainable development really looks like behind the highlight reel. Not just pretty renders and big announcements, but pressure, responsibility, and the constant work of improving systems so each project is better than the last.
