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 re...

“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 env...

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...

“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 Syd...

“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 buil...

“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.

If you have ever felt like the business owns you, this conversation will feel familiar. Quoting at night, solving problems all day, trying to remember what you...

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

That line from Villy Yordanov, Pro Clima’s Innovation Engineer, sets the tone for this conversation about what is technically allowed versus what actually leads to durable, healthy homes. We unpack the gap between building compliance in Australia and real-world building performance, particularly in weatherproofing, moisture management, and the building envelope.

A big focus is the NCC 2025 changes and how some cladding types can bypass performance solutions. On paper, that can look like simpler compliance. On site, it can create risk if builders assume “compliant” automatica...

A German journeyman carpenter walks into our studio and within five minutes, we are thinking, hang on… have we made modern life way more complicated than it needs to be?

Erik is living a tradition that feels almost impossible in 2026. He is travelling for three years and one day, working wherever he can, learning from other tradespeople, and doing it all without a mobile phone. Not as a gimmick. As a way of life.

Erik’s story centres around the German tradition of the Journeyman Years, a rite of passage where carpenters leave home to shar...

Weekly Goss – April 23, 2026

Matt and Hamish are back from Adelaide to discuss the latest housing developments in Canberra, a major safety crackdown on silica dust, and the importance of representation in the trades.

In This Episode:

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.

We get into the practical side of sustainable design and what actually makes a difference in real homes. Things like orientation, shading, airtightness, draught-proofing, solar power, and...

In this episode, Hamish and Matt navigate the "geopolitical bruises" impacting the Australian construction industry in early 2026. They discuss the sharp rise in material costs driven by global tensions, the controversial shift in Victorian builder licensing, and the silver lining of surging apprenticeship numbers. The duo emphasises that while the climate is "doomy," transparent communication and creative contract management (like provisional sums) are the keys to survival.

Key Discussion Points

1. The "Strait of Hormuz" Effect & Rising Costs

The industry is facing a second wave of price hikes, this time driven by...

The Australian building industry is shifting fast, and in this episode, we discuss what that really looks like on the ground. From economic pressure and labour shortages to changing technology and AI-driven disruption, this is an honest conversation about the reality of running a building business in a market that feels increasingly uncertain. If you are a builder in Australia, a construction business owner, or part of the wider residential construction industry, this episode will likely hit close to home.

A big focus in this discussion is pre-construction and the hidden work that happens long before a...

Episode Title: The NCC Maze, Red Tape Blues, and a Win for Passive House

Date: 9 April 2026

Hosts: Matt & Hamish

In this second instalment of The Weekly Gossip, Matt and Hamish navigate the "grey areas" of the 2025 National Construction Code (NCC) updates and the mounting administrative burden currently squeezing the life out of small building businesses. We also look at some progressive moves in South Australia and shout out a Kiwi builder doing the absolute "impossible" on the side of a cliff.

In their first wrap-up, they tackle the Victorian Government’s "Dodgy Builder" bill, which empowers th...

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

We sat down with Marcus Strang, Technical Lead in Passivhaus at HIP V. HYPE, to explore what sustainable building design really means in practice. With a PhD from the University of Queensland and deep expertise in building science, Marcus shares how Passive House design is helping shape healthier, more energy efficient buildings in Australia.

We unpack how Passivhaus principles go far beyond energy efficiency. This conversation covers thermal comfort, indoor air quality, moisture safety, and why high-performance homes need...

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

In this episode of The Mindful Builder, we sit down with Roberto Petruzzi, an Environmentally Sustainable Design (ESD) specialist, to unpack what building performance and energy efficiency really mean in practice. We talk about energy modelling, building science, and why the details you cannot see often matter most for comfort, durability, and running costs.

Roberto explains the unseen layers that shape high-performance homes, including airtightness, thermal performance, insulation continuity, ventilation strategy, glazing choices, and shading. These are the decisions that determine whether a home feels stable and comf...

“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.

We unpack Alistair’s path through construction management and working with larger builders, including Icon Construction, and how those early years shaped...

“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.

Roger shares his journey from Northwest Ireland to training in England, and how that hands-on background shaped his people-first approach to design. He describes his process as method acting, getting inside a client’s routines and pr...

“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.

Liam shares why sustainable success is built through iteration, not perfection. Using ParkLife 2 as an example, we unpack how strategic planning, process improvement, and a long-term mindset help create high...

“I’m not just a carpenter.”

That’s the energy Sam Aitken brings to this episode, and it is exactly what the construction industry needs more of. Carpentry is not a fallback job. It is craft, problem-solving, and leadership on-site. Sam is also using social media to show what pride in the trade actually looks like, without turning it into a glossy performance.

We sit down with Sam to talk about his journey from Carisbrook to completing his apprenticeship in Ballarat, and why he stayed working with the same boss who trained him. We also unpack w...

High-performance building is not just about premium products. It is about the system. In this episode, we sit down with Sven Maxa from Maxa Design to unpack what Passive House building really looks like behind the scenes, from airtightness targets to the practical realities of delivering high-performance homes on site.

This conversation flips the usual format, with Sven taking the lead and putting us (Hamish and Matt) in the hot seat. We get into the details that actually make or break a Passive House project, including airtightness testing, verification, contract clarity, and what happens when documentation looks...

“Most Aussie homes still don’t meet today’s energy standards.” In this episode, we sit down with Tim Forcey, a former chemical engineer turned home energy advisor who has assessed and advised in 1,000+ homes across Melbourne and Victoria. Tim is also qualified to assess homes using the Victorian Residential Efficiency Scorecard and runs the “My Efficient Electric Home” community with 120,000+ members. This conversation focuses on practical home energy efficiency, comfort upgrades, and how to reduce energy bills in real Australian homes.

We break down the high-impact steps that make the biggest difference fast, including roof insulation checks, draf...

“Stop talking to everyone like they’re in the industry. Talk to them in ways that are going to evoke emotions and what’s important to them.”

In this video, we sit down with Laura De Ridder from Sorted Digital Marketing to chat about why so much of the construction marketing we see misses the mark, and what builders and tradies can do instead to attract the right clients.

We cover how to get clear on who you’re actually talking to, why storytelling builds trust faster than specs and spreadsheets, and how to use different...

“I remember crying, driving back to Geelong because it was just too much.” In this Mindful Builder Podcast episode, Devin Grant of Performance Membranes shares the real story behind building a successful construction business and what happens when the workload finally catches up with you.

We talk burnout, six-day weeks, and the lessons Devin learned after starting Granted Constructions in 2013. Then we get into the practical side of Passive House building in Australia; why it’s not a “spaceship”, why it’s “just a house done right”, and what Devin’s learned from living in his own Passive House for...

“We’re dumping energy to maintain comfort.”

That’s how Andre Griffs from BINQ sums up what’s happening in far too many Australian homes. We crank the heater, blast the air con, and wonder why the house still feels off. Often, the culprit is simple. The windows are not performing.

We sat down with Andre to unpack what’s going wrong with Australian windows, why it matters more than most people realise, and what BINQ is doing differently to lift the standard.

Windows aren’t a finishing touch. They’re a performance decision.

"In Germany, you’d never see a timber frame left out in the rain." 

That’s just one of the eye-opening differences we uncovered with Daniel Jakobs, a master carpenter and construction engineer from Germany, on the Mindful Builder Podcast. Dan has spent over 20 years in high-performance, ecological construction, and now serves as Technical Sales Manager for pro clima® in Australia and New Zealand. If you’ve ever met him, you know he’s got a world-class hipster beard, a great sense of humour, and the rare ability to make building science fun.

Dan shares what sets...

"Is natural building just for green hippie owner-builders?" 

We sat down with Rachel from Natural Building Australia to tackle this question head-on. Rachel's academic background and hands-on experience reveal how natural building has evolved from 1990s counterculture to a professionalised industry attracting broader audiences. Thanks to hemp industry growth and increasing awareness of healthy building materials, natural building is becoming a legitimate mainstream option in Australian construction.

Rachel discusses the challenges facing natural building - building codes that don't recognise materials used successfully for centuries, labour shortages, and higher costs for bespoke approaches. But she's o...

A couple of years ago, we weren't sure if a podcast focused on thoughtful, evidence-based building would resonate with Australia's construction community. Turns out, builders, architects, and clients were hungry for exactly this kind of conversation - real talk about what works, what doesn't, mental health challenges, and how to navigate the shifting landscape of codes, client expectations, and new technologies.

This year's conversations revealed clear themes: passive house principles are entering everyday builder vocabulary, communication between teams makes or breaks projects, and learning new techniques while unlearning old habits is essential for industry evolution. 

T...

"Architects design things we can't actually build."

We sat down with Saxon Hall, Principal Architect at Align Architecture, to tackle the age-old tension between architects and builders. Saxon's unique perspective as a carpenter's son gives him insight into both sides of this divide.

In this episode, we explore why communication breaks down between architects and builders, and more importantly, how to fix it. Saxon shares his 'Align Build Collaboration' method that brings builders into projects from day one, the debate around tender vs negotiated contracts, and why energy-efficient design doesn't have to sacrifice aesthetics.

The conversation delves into the mould issues arising in bushfire zones, exploring how sealed environments contribute to the problem and the ongoing search for evidence to address these challenges.

takeaways

"The message that passive house is better, just isn't reaching people." 

We explore what actually happens when passive house ambitions meet the realities of Australian building sites - from the builder's perspective, the architect's challenges, and the client's concerns.

Today we’re discussing what it means to design and build a passive house with Sven Maxa from Maxa Designs: the learning curves, cost considerations, and collaboration required to bridge the gap between high-performance building theory and practical execution. We break down what changes for builders tackling their first passive house spec, how architects balance performance wit...

“I learned about discipline and resilience at a very young age, all because of this passion that I held. Those lessons have certainly translated into my adult life.”

In this episode, we sit down with Sally former Matilda, now a carpenter and business owner, to explore what it’s really like to transition careers in the building and construction industry. Sally shares her story of moving from elite sport to the tools, overcoming injury, facing health challenges, and building a new path based on shifting values and a growth mindset.

Whether you’re a mid-career tradie...

"Even if you finish the build, it's not too late to certify." 

That's what Emilia Iacovino from Detail Green tells builders who've completed high-performance homes without formal Passive House certification. But should you wait that long? We sit down with Emilia, one of only five Passive House certifiers in Australia, to explore whether certification is just bureaucratic red tape or if it delivers genuine value for builders and clients.

Emilia's unconventional path, from architecture aspirations through electrical engineering and automotive work in Japan, gives her unique insight into both the technical requirements and practical realities o...

"I decided not to be the 'too busy' dad who missed seeing his kids grow up."

That was the wake-up call for David Jenyns, founder of Systemology. For too long, he was trapped working 60+ hours a week in the business he built which is a common fate for many successful entrepreneurs. If your business cannot function for a week without you, you're not a business owner; you're an employee of a business you own.

We recently sat down with systems expert Dave Jenyns to understand how entrepreneurs can transform struggle into structured, scalable success. The...

"I had to sell personal belongings just to make payroll." 

Luke Davies isn't ashamed to admit the early struggles of his construction business. From a dairy farm in Sheffield, Tasmania, to running successful building and architecture enterprises, Luke's journey demonstrates what happens when resilience meets strategic learning. We sat down with Luke to understand how he transformed early failures into a thriving business model that's now helping other builders avoid the same mistakes.

For builders facing the daunting 90% failure statistic, Luke's story offers practical lessons: admit what you don't know, invest in coaching and education, u...

"You're wearing a tin foil hat if you think Passive House will work in Australia." 

That’s probably what Clare Perry would have heard back in 2011 when she co-founded the Australian Passive Haus Association. Fast forward to today, and while Passive House hasn't yet become mainstream, the landscape has shifted dramatically. Industry appetite has grown, more building professionals are actively exploring the concept, and even government is starting to take notice. We sat down with Clare to understand how this shift happened and what it means for Australian builders.

For builders considering Passive House, the que...

 ”I'm just an average carpenter and builder a lost in a world of red tape”.  

Joel Griffs from Heidi Build isn't exaggerating. The modern builder's reality involves navigating compliance mazes, managing cash flow crises, and maintaining a social media presence all while trying to actually construct buildings. We sat down with Joel to understand how the builder's role has transformed and what it takes to survive in 2025.

For those entering or continuing in the building industry, Joel's story offers both warning and encouragement: the work is harder than ever, but with the right approach, it's still po...

Becoming a father changes everything - including how you run a construction business. 

Matt just welcomed his first child, while Hamish became a dad for the third time, adding a daughter to his two boys. These life changes forced a complete reassessment of priorities, work schedules, and business operations. But fatherhood isn't the only transformation happening - AI, rising costs, and trade dynamics are reshaping the entire construction landscape. 

In this episode, we talk through the trends we’re seeing right now and what they’ll potentially look like into the future.
