Episode Details

Most builders know materials, margins and project management. Very few know what the materials going into their homes are doing to the people living inside them.

In this episode, Aaron sits down with Zara D'Cotta, building biologist, EMF specialist, and founder of The Healthy Home. Zara spent years navigating her own cancer diagnosis, environmental illness, and the search for a safe place to live. That experience became the foundation for her work helping builders, architects, and designers across Australia and New Zealand understand the relationship between the built environment and human health.

This conversation covers ground most of the industry hasn't touched yet.

Topics covered in this episode:

• Zara's personal journey through cancer, melanoma, and environmental illness — and what it revealed about the homes we build
• What building biology actually is and why it was founded in post-war Germany
• The four areas that matter most in a healthy home: materials, moisture, air quality, and electromagnetic radiation
• Why low VOC doesn't automatically mean safe — and what builders and designers should be asking instead
• How moisture gets trapped in walls during construction and why mold appears in homes less than two years old
• What electromagnetic fields are, why the electrical code doesn't account for them, and how they can affect sleep, health, and wellbeing
• The difference between a genuinely healthy home and one with a sauna and a dog bath
• How builders can position themselves in the healthy homes space with integrity and transparency
• What makes a good builder — Zara's answer will stay with you

This is bigger than building. But it starts with builders.
