Whanganui District Brunswick Non-certified, eHaus Euro, Passive House Plus


Designed by local Architect Duncan Sinclair of Black Pine this eHaus is set in the rural landscape north of Whanganui. This two level family 3 bedroom home was sited to capture the magnificent views of the mountains through the huge picture window in the lounge. This retired couple love the all year round comfort and warmth the home provides. The 5KW photovoltaic solar panels and solar thermal hot water systems means the home generates more energy than they can consume, providing huge savings.

Extraordinary heat energy savings.

Every one of our projects are energy modelled using the Passive House Planning Package (PHPP). It's through this powerfully clever tool that we can accurately calculate just how much heat energy every eHaus will save when compared to a similarly- sized typical new home, built in the same climate region.

This project is making significant carbon savings for a better environment.

We believe that our homes should have a big impact on the way we live, but little impact on the land. We've calculated the amount of carbon our homes have saved through energy efficiency from move in day 'til now. At their core, eHaus' are built with the elimination of carbon emissions in mind - so we're not only creating healthy, comfy & high performing homes, but spaces that don't cost the earth.
