Waikato Matangi Non-certified, eHaus Euro, Passive House Classic


This multi award winning HOY (2022) four bedroom eHaus Euro fits to the natural contours of the site with north facing windows making the most of the rural views. The high performance wood aluminum European joinery is a feature throughout the home and further timber features are echoed in the extensive built in joinery in both the kitchen and living areas. This home has a 8.2 kw PV solar system, supplying the home, which is also battery ready for the future. Aluminum shading screens have been added to gable ends, complementing the dark cedar and block exterior cladding. Extensive timber decking areas on the north and east allow easy indoor/outdoor living with a sheltered enclosure to enjoy the outdoor fireplace.

HOY 2022 - Regional Gold Award winner - Category $1.5-$2M,  plus APL Sustainable and Environmental Excellence Award.


"Thank you, this was a great experience, and the finished house is an absolute pleasure to live in."

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.
