“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 8+ years.

We also unpack Devin’s work with Performance Membranes, training 2,500+ builders and trades in airtightness, weatherproofing, and building better-performing homes.

“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.

And if Australia wants healthier, more comfortable, more energy-efficient homes, we can’t keep treating windows like a commodity. Conversations like this, with people like Andre pushing the industry forward, are how standards lift.

If you’re building or renovating and you’ve never thought deeply about your windows, we hope this episode helps you to think differently and do more research in the future.

"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 European building standards apart, from meticulous prefabrication and weatherproofing to the absolute importance of ventilation for healthy, durable homes.

Discover why protecting timber, getting back to basics with tools, and prioritising proper airflow are non-negotiables for future-ready construction.

Australia has the talent and the tools; now it’s about raising our standards. That means learning from the best of Europe, investing in better methods, and refusing to settle for more relaxed standards. For new apprentices and seasoned builders alike, it’s about being open to new ideas, looking after your craft, and building homes that are healthy, durable, and genuinely fit for the future.
