Passive House

Jessop Architects designed and managed the build of the first certified Passive House in Australasia. They have since become New Zealand’s most recognised architects for designing energy efficient, low energy and zero energy homes that are warm, comfortable and aesthetically beautiful.


Our practice concentrates on good design that is innovative, imaginative, and pushes the boundaries for residential and commercial projects. Recently we have been focusing on how New Zealand homes can be better insulated and energy efficient, while maintaining a high quality design.

The team at Jessop Architects have the knowledge and experience with the issues and importance surrounding Passive Design homes, including how to work best with councils. With some of the world’s leading technology in Passive design right at our finger tips, we believe that our practice now has the ability to compete on an international level in this area.
