Scott Stewart used to fly in high performance aircraft with the Royal Australian Air Force. Now he helps architects, designers and builders with the high performance details of Passive House homes.

Hamish White is Director of Sanctum Homes, based in Victoria Australia. He's a registered Domestic Builder with a marketing degree! Since discovering Passive House, Hamish has been inspired to become a Passive House business. Architects, designers and other builders can be encouraged that there's a market out there and willing clients who want healthy, comfortable and energy efficient homes. I discuss with Hamish, how he got into the building industry and any advice he has for others interested in building better.

The Hawea Flat Passive House in the middle of the South Island is a very special home. It boasts a number of 'firsts' for New Zealand and the journey of its creation has arguably changed more than just the way Jonathan Holmes lives.
