What if the biggest risk in New Zealand homes isn’t what we can see — but what’s happening inside the walls?

In this episode of the Smart Living Spaces podcast, Architectural Designer Sharon Robinson speaks with Simon Cator from Pro Clima New Zealand about airtightness, moisture movement, and why many modern homes are unintentionally creating conditions for mould and poor indoor health.

Together, they unpack why airtightness is not about “sealing buildings shut,” but about taking control of air and moisture flow — and why ventilation must be designed intentionally rather than left to chance. The conversation challenges Building Code minimums, addresses common industry myths, and explains how better-than-code thinking leads to healthier, more comfortable, and more durable homes.

This episode is for architects, designers, builders, and homeowners who want to understand how Architecture in New Zealand can move beyond compliance and start building better — not just on paper, but in real lived experience.
