New Zealand's first certified passive house — designed by Jessop Architects — has sold for over $4 million, a benchmark moment for high-performance residential design in Aotearoa.
The sale of New Zealand's first certified Passive House — designed and delivered by Jessop Architects — is a milestone for the local high-performance housing sector. It signals a maturing market where buyers recognise the long-term value of homes that are quieter, healthier and dramatically cheaper to run.
Passive House certification is a rigorous, performance-based standard. Homes are independently verified to meet strict thresholds for heating demand, airtightness and indoor air quality.
Coolhouse plans draw directly on this Passive House lineage. Whether you choose to build to full certification or to a low-energy specification, the underlying detailing — continuous insulation, careful junctions, mechanical ventilation with heat recovery — is consistent across the collection.
