Day two of our New Zealand road trip, and this time the build site is under a canopy.

Luke and Dean head out to Whio Homes in Christchurch, made possible by McCormacks Australia. James and Leesa Anderson build high performance modular and transportable homes out of a 100 foot container barn, and every one of them goes to the Foreverbreathe specification.

They walk us through why they detail their own frames, how a finished house gets jacked up and trucked out over the fence, and how a team of five staff turns out 12 to 15 homes a year with room to more than double that on a second shift. James makes the case against building to code minimum, and explains why sealing homes up airtight has trapped the off-gassing from petrochemical products inside with the people living there.

Then it's into the detail: LVL framing, Magnum Board as the rigid air barrier, Terra Lana wool insulation, clay-based paint, wool carpets, thermally modified cladding, and the jump in cost from aluminium to uPVC to timber windows. Leesa finishes on one of their biggest challenges: convincing clients that bigger isn't better.

A running shower, no fan, and a mirror that won't fog up. That's when the ForeverBreathe system stops being theory.

We're still in Christchurch with Kelly and Andrew from Premium Homes for part two of our New Zealand road trip, made possible by McCormacks Australia. If you missed part one, go back and listen to that first.

This time the conversation moves from the wall build-up to what it's actually like to live and work with the system. Kelly and Andrew unpack where the ForeverBreathe specification came from, why HealthBased Building owning it takes risk off the designer, and what the air quality monitors in their homes are picking up. A box of door handles, a courier bag, a bench being wiped down: all of it sends TVOC readings spiking, which raises the question of why we keep building with those materials in the first place.

There's also an honest look at the hard part: getting plasterers and painters to follow a process that's slower and less forgiving than gypsum and acrylic, and why they now certify trades before letting them near the product. Plus the bathroom demo, the carbon numbers, and the answer to the question everyone asks: what does it cost?

First time the Build Insite Podcast has left Australian soil. And we've landed in Christchurch for a good reason.

This one's a special episode. Luke and Dean have packed the mics and headed across the ditch for a New Zealand road trip, made possible by McCormacks Australia. Huge shout out to Glenn and the McCormacks team for getting us over here. We're recording inside the Premium Homes display home in Christchurch, and a lot of the products you'll hear about are already available in Australia through McCormacks.

Our guests are Kelly and Andrew, school mates turned business partners who started Premium Homes nearly 20 years ago after Kelly, a sparky by trade, got sick of wiring houses that weren't plumb or square. They walk us through what the Christchurch earthquakes did to the local industry, how New Zealand's leaky home crisis unfolded, and why the push for airtight homes is setting up the next round of problems: sweaty walls, hidden mould and what the Americans have called sick building syndrome for two decades.

Then it's into the ForeverBreathe system itself. Magnum board inside and out, wool insulation in the middle, breathable paint, and no vapour barrier at all. It goes against everything most builders were taught, but the numbers on moisture handling, R value stability and energy performance are hard to argue with.

Two years out of his time and Jake's already running boys on site. Matt reckons the trick isn't finding good tradies, it's giving them a reason to stay.

Part 2 with Matt and Jake from MS Constructions picks up on what happens after the apprenticeship ends. Jake talks about stepping into project management, learning the construction manager's side of the job, and copping the odd older tradie who walks straight past him to talk to someone who looks the part.

Matt gets into the systems side of the business. He's brought WonderBuild and AI into MS Constructions with help from Adam at WonderOps, and his crew are now running site diaries, photos and timesheets from their phones. His reasoning is simple: automate the background so the office team can spend more actual time with clients.

There's also a solid stretch on why builders need to stop hiding. Matt's built a network of builders around Australia he can ring about anything, and both he and the hosts make the case that asking the same question to a different person is often what finally makes it click.

Five carpenters. Four hours in the car. One day off the tools. That's what education looks like when a builder actually means it.

Matt from MS Constructions has driven his team down from the Vic and New South Wales border to the Bowens Rethink Building Hub, and he's brought his qualified chippies and construction manager with him. Joining him is Jake, who did his apprenticeship under Matt and has since watched two major NCC changes land inside his first few years on the tools.

In Part 1, Matt talks openly about scaling the business back, why turnover stopped being the scoreboard, and how hiring for attitude instead of skill changed the way his crew shows up every day. Jake shares what it was like coming through an apprenticeship with no clue what he wanted to do, and what he's learning now about condensation, wraps and passive principles that simply weren't taught a few years ago.

There's also an honest conversation about mistakes. Matt reckons he doesn't trust a builder who says they've never had a problem, and he explains why pulling failed work apart with his team has become one of the most valuable training exercises in the business.

Day one on site, and there's asbestos. What happens in the next ten minutes tells a homeowner more about their builder than anything in the tender.

In this second half of the conversation at Callery Creek House, Zoe and Andrew get into the part of a build that most people only understand in hindsight: how communication actually works between a homeowner and a builder, and what happens when it doesn't. We recorded this on handover day, with the keys about to change hands, so everything is still fresh.

They share the advice they'd give anyone about to sign a building contract, from working out your own values before you start researching, to visiting an open home and talking to a builder's current client. There's also a warning about builders juggling too many sites at once, and a strong case for getting every site meeting decision confirmed in writing.

It's not all process. Zoe wrote a blessing and had it embedded in the concrete pour, which landed at the threshold by pure chance, and a gum leaf left a perfect stencil in the burnished slab that they chose to keep. We also talk about the night Zoe found herself at the Master Builders National Awards as a current client, watching her own builder go up on stage.

Most build stories get told by the people getting paid to be there. This one comes from the couple who lived in the middle of it, for nine months, with three kids and a dishwasher in the bathroom.

In this episode we're sitting at the finished marble benchtop of Callery Creek House with Zoe and Andrew, the homeowners. It's a rare thing to hear a renovation unpacked from the client's side of the table, and they don't hold back. We cover how a "bit of a tizzy up" turned into a full two storey extension, why an 18 month design process was worth every minute, and what it actually feels like to live on your own building site while it's being built around you.

Zoe brought a long held commitment to sustainable design and passive house principles to the project. Andrew brought a refusal to let her compromise on them. Between the two of them, and an architect willing to design for performance, the brief was set well before a builder was ever engaged. That timing turns out to be one of the biggest lessons of the episode.

We also get into how they chose their builder, what almost sent them in a different direction, and the one thing that ultimately got Callery Building over the line. Spoiler: it wasn't the glossy finished photos.

The code is moving. Slowly. But there's a lot you can do without waiting for it.

Part two with Jess from Climasure picks up where we left off, starting with the state of the NCC and what the next update means for builders. South Australia's energy efficiency pause, the drained and vented cavity change everyone's talking about, and why blower door testing already sits in the code as a verification option that almost nobody uses.

From there, Jess gets practical. If you want to build better but can't overhaul everything on your next job, where do you start? Her answer is a step by step: benchmark with a blower door test, then get serious about membranes and moisture management, then build the team around it. Because a builder pushing high performance without the right client, trades and designer is fighting uphill.

The back half goes into the two rabbit holes Jess is currently down. EMFs, including the moment a monitor reading dropped because the electricity was travelling through her body. And mould, which she calls a silent killer for good reason, with a story from a client whose respiratory problems cleared up only after a leaking shower wall came out.

You can't control what you don't measure. And in most homes, no one's measuring anything.

Recorded on site straight after the final blower door test at the Callery Creek House project (4.1 air changes an hour, for the record), this episode brings back one of Build Insite's most popular guests, Jess from Climasure. Third time on the show, and she's brought a whole new rabbit hole with her.

Jess walks us through her path from doing energy efficiency star ratings for the building code, to realising that what gets designed, what gets assessed and what actually gets built can be three very different things. That realisation set off a domino chain: blower door testing, ventilation, Passive House, hygrothermal modelling, and now building biology. We also get into her own podcast, the international guests she's landed, and the internet's very strong opinions about insulating brick cavity walls

Then things get interesting. Jess has just started working in the EMF space, taking radio frequency, electric field and magnetic field readings on a certified Passive House site before the slab was even poured. Plus the everyday stuff most people never think about, like what happens to particulate matter when you fry an egg on a gas cooktop, and why the CO2 in your bedroom is probably sitting at more than double what it should be.

The real test of a building business isn't the boom times. It's how you communicate, hire and hold your ground when things get tight.

In Part 2 of this conversation on the Build Insite Podcast, Dean and Luke continue the chat with Brett Way from VW Building Projects. This time, the focus shifts from heritage craftsmanship to the engine room of running a strong building business through uncertain conditions.

Brett opens up about VW Building's Early Contractor Involvement (ECI) process, how they educate clients on the unknowns that come with heritage homes, and the challenges of navigating council delays in Victoria. He also gets candid about the current pressure on pricing, fuel costs and material escalations, and how transparent conversations with trades, clients and team are more important now than ever.
