Mindful Builder

“I couldn’t unsee it.” Jimmy from June Building explains how Passive House building science finally clicked, after learning through Instagram and then winning the Pro Clima Passive House Tradesperson scholarship. Today Jimmy flips the format and turns up with a notebook full of questions on Passive House for us. Questions around high-performance homes, airtightness, mechanical ventilation, and what actually changes when you start building for comfort, not just compliance.

Jimmy’s background is classic chippy-to-builder with a few turns that matter. Apprenticeship in Ballarat, travel to Banff in Canada, then Melbourne across maintenance, commercial, and high-end resident...

You can’t build ten versions of the same house, live in them for ten years, and then pick the best one.

We’re sitting down with thermal modelling specialist Cameron Munro to talk about why “model early and model often” should be a non-negotiable part of pre-construction, whether you’re chasing Passive House or just trying to build a home that actually feels good to live in.

We explain what modelling is really for (direction, not perfection), how to run “what if” scenarios across glazing, insulation, shading, and floor build-ups, and why the best decisions come...

“At some point, someone’s paying for that tender.”

Tendering sounds fair on paper. Same drawings, three builders, pick the best price, move on.

But once you understand what it actually costs to price a job properly, and how tendering rewards omissions, risk loading, and variations, it starts to look less like a “market test” and more like a costly way to kick off a relationship.

In this episode, Hamish and Matt break down what a tender really is, why the classic draw, bid, build model creates isolation and blame, and why negotiated tendering...

Good design isn’t something you look at. It’s something you live in.

We sit down with James Goodlet from Altereco Design to talk about what “good design” actually means in the real world, and what a proper pre-construction process looks like when it’s done properly.

We get into why comfort is more than temperature, how designers extract the details that shape the lived experience, and why due diligence and risk management need to happen before anyone starts drawing. We also break down why James brings builders in early, how he thinks about budgeting...

A proper site visit isn’t a stroll around the block. It’s where you catch the stuff that turns into $30k surprises later.

We’re back with Brad from Sanford Buildco to have a conversation about what a site visit should actually involve, and why doing it properly is one of the simplest ways to protect your time, your margin, and your sanity.

We break down how our checklists differ across inner-city and rural sites, but still cover the same core categories: access, services, water management, demolition risk, and the existing building. We talk throug...

“There’s no such thing as a quick estimate.”

Estimating is one of the biggest parts of pre-construction, and it is also where builders lose time, money, and trust when the process is loose. We sit down with Rick Hughes from Estimating Online to take a look at why the idea of a “quick estimate” is often the start of bigger problems later.

Rick breaks estimating into a four-step process, from the gut-feel feasibility estimate through to rapid software-based estimating, a detailed bill of quantities, and then true costing where the client is committed and trades are...

“Budget does not mean your build cost.” Matt drops that early, and it should be printed on every set of concept plans. In this episode of The Mindful Builder Podcast, Matt and Hamish sit down with Brad McEwan from Sanford Buildco for a blunt chat about project feasibility and why so many custom home builds in Australia blow out financially. If you’re a homeowner, builder, or designer trying to avoid budget shock, this one will save you a lot of pain.

We talk about the gap between a client’s budget and the reality of what the desi...

“If you keep ending up with bad clients, that’s a you problem.”

Matt doesn’t sugar coat it, and honestly, he’s right.

In this episode we kick off our pre-construction series by talking about the building clients we refuse to work with, and why picking your client is one of the biggest risk controls in a construction business.

This is a practical chat for builders, tradies, architects, and homeowners who want a smoother build. We talk about why most client conflict comes from a lack of structure, unclear expectations, and messy communicat...

"How rock bottom do you have to let me hit before you actually help me?" Brad McEwan’s words hung in the air after we wrapped, because they’re all too familiar in the building industry. In this episode, we go past the surface stuff and talk honestly about what it looks like when you’ve been carrying it all, hoping someone will notice, and then realising you’re running out of road.

From the outside, Brad looks like the guy who’s got it sorted, with business, family, and good people around him. But he shares how quickl...

In this episode, Joel (Heidi Build) hijacks the mic for an unfiltered conversation about the realities of building in Australia.

We break down why builders can feel “owned” by a client for years after a contract is signed, how viral “circus build” videos damage trust in the whole industry, and the difference between educating and selling when builders share their work on social media.

We also get practical: if you live in a typical 1990s brick veneer home (single glazing, gaps, limited insulation), we cover the first upgrades that improve comfort and indoor air quality, includin...

If you’ve ever wondered why Australian homes feel freezing in winter and brutal in summer, this episode makes it painfully clear. “Suppliers in Australia are still delivering single-glazed aluminium windows,” and that one sentence explains a lot about comfort, energy bills, condensation, and why so many people feel worn down inside their own homes.

We sit down with Monika Rogers from Eco Sky Windows to talk high performance windows, Passive House certified systems, and what “thermally broken” actually means. We discuss U-values, why the whole window unit matters (not just the glass), and how slimline design, hardware...

In this episode, we sit down with Joel from Heidi Build and Andrew “Hoppo” from Hoppo Construction for a no-script, no-agenda chat.

It starts with what makes tradie creators actually work online: being approachable, having an opinion, and showing up as yourself. Joel breaks down why the polished, curated Instagram approach did nothing for him, then the one raw timber-quality rant that finally cut through.

From there, we get into the stuff people don’t always say out loud. The stigma that tradies aren’t intelligent, why that stereotype still lingers, and the moment Joel’s own brot...

James Turner from JTurner Constructions didn’t plan to start a building business. A torn ACL and a forced shift into subbie life pushed him into it, and he built the company the way most builders do: decks, renos, extensions, then new homes.

Two and a bit years ago, he was ready to pull the pin. Bad estimating, people management gaps, COVID losses, and the mental load stacked up fast. A turning point came from an unexpected place: an eight-week men’s course (Rising Kings) that helped him rebuild structure through daily habits and exercise.

From...

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

A tradie builds momentum fast. Makes money fast. Spends it faster. Learns the hard way about GST, tax, super, and the cost of looking like you’ve “made it”. Then the pressure stacks up, burnout hits, and the whole thing starts to wobble.

Andrew Hopkins (Hoppo from Hopkins Construction) walks through the real comeback: rebuilding a construction business with better boundaries, a stronger brand, and a work week that actually fits parenting. It also gets practical on social media for...

“You’re at the mercy of the quality of the 2D plans.”

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.

We take a look at why 3D modelling for builders is not about pretty renders; it’s about clarity. Tom explains...

“If you can’t hit 0.6 ACH on a brand-new build, you probably shouldn’t be building.”

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.

We take a look into why retrofitting the existing 9.5 million homes in Australia is the single biggest business opportunity for trades over the next decade. Linden walks us thr...

“On paper, six or seven competitive builders trying to run one organisation together makes no sense.”

In this episode, we sit down with Bec Kempster, the brilliant Chief Operating Officer (COO) of the Sustainable Builders Alliance (SBA), to talk about the messy, necessary business of upgrading the Australian construction sector. Recording from Matt’s newly completed Grand Designs home, we strip back the hype and discuss how the SBA transitioned from a grassroots cause into a highly structured, professional association shaking up national building standards.

Bec shares insights from her eclectic background. Spanning commerce degrees, corpor...

“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.

Dave’s story is a good one. He started as a carpenter, spent years in the trade, then went back to uni and completed a Bachelor of Applied Physics before landing at Pro Clima. That mix of site experience and building science makes him one of the most practical voices in the high performance building space...

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.

This episode covers the latest updates in the Australian building industry, including new legislation, code transitions, and innovative materials. Hosts Matt and Hamish analyse recent news, government policies, and emerging technologies impacting builders and homeowners.

Matt and Hamish from The Mindful Builder are launching a new, "short and sharp" weekly news segment. Capped at 10 minutes, the offshoot aims to provide a non-biased rundown of Australian building industry news, focusing on facts and positive stories while navigating a shifting legislative landscape.

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...
