“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 Sydney with Andy Marlow, director at Envirotecture and a certified Passive House designer. Andy has a rare ability to talk about sustainable building without the greenwashing and without making it feel like a lecture. The focus is on outcomes that matter to homeowners and builders alike. Homes that perform, homes that last, and homes that do not quietly fail behind the plaster.

We also dig into the Living Building Challenge, because it is one of the few sustainability frameworks that does not let you cherry-pick the easy bits. It looks at the full picture of holistic sustainability in construction, including materials, energy, water, and health. Not because every project needs a badge, but because it forces better questions about what sustainable construction really means when you zoom out and look at long-term impact.

Finally, we talk about making Passive House principles more buildable and accessible through Andy’s Passive House Design and Construct model. Pre-designed, high-performance homes that still leave room for personal choice, without reinventing the wheel every time. We also share the lessons we have learned the hard way, and why building with intention is about mindset, systems, and balancing the ideal with what is financially feasible and genuinely buildable on real sites.
