Ethos Homes are excited about building energy efficient homes, with the future in mind

Are you a convert, or just checking options out? Are you looking to build and are thinking long term about comfort and health? We trust you will find some useful information and links here…

We recognise that building to the New Zealand building standards isn’t enough. At Ethos Homes we don’t want to build you a house, we want to build you a home, one that works for you, one that’s warm and cosy in winter and cool and comfortable in summer. A home with superior air quality from filtered air significantly reducing the levels of dust, moisture, pollen and other allergens, and one that’s energy efficient with low running costs. We build each home like it’s our own.

We build houses to the Passive House standard, designed to give your family the best health, comfort and happiness at a fraction of the energy used by conventional homes.
