Wairarapa Carterton Non-certified, eHaus Euro, PHI Low Energy


Nestled in the heart of the bustling Carterton township this modern home has all of the features you would expect, and then some. The client has a passion for craft beer and so incorporated into the design is the brewery department!


"We appreciated feeling welcome to ask questions throughout the whole process and that we got honest answers back every time. The result was a brilliant design solution that could be built to our tight budget on a restrictive section. Now that we're in the house we're realising just how perfect the design is and that the house really performs wonderfully."

— Christina Hyman

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.
