Taranaki Oakura 2 eHaus Euro, Certified, Passive House Classic


This six times 2021 House of the Year winner is a super star. This is what the judges had to say about the property. "Combining functional design with high energy efficiency and excellent workmanship has resulted in this fantastic building and family home. This home by Hofmans Builders is a highly energy efficient house with careful planning for solar gain and smart material choices. The selection and execution of spruce and oak timbers complements the carpet, tile, and joinery units incredibly well. With exposed timber elements, this house was complex to build but was finished to a very high standard. It features a clever design, high attention to detail and meticulous construction, making it the regions supreme home. This house has truly been built by craftsmen, with the accuracy and skill of the builders being visible across the foundations, walls, and roof. Huge consideration has been given to the set out of the claddings, which are uniform and accurate. The flashings are neat and beautifully installed alongside the multi member columns and screens. It is clear the door hardware and trims have been fitted with consistency in mind, while the tiling is totally faultless, and the internal wall and ceiling linings are of a very high standard." This home has also been independently recognised as a Certified Passive House. This home is the winner of six awards in the Registered Master Builder 2021 House of the Year Competition, including winning the Supreme Build for the Taranaki Region. Our architectural, central & build teams are very proud of this incredible project.


"During an interactive design phase, performed primarily via email from overseas, we achieved exactly what we wanted based on our brief – a warm and comfortable home which is also stylish and modern. We are very pleased with the new house. It is just as we had envisioned from the plans, and the performance has been excellent. We have not needed to use any heating and everyone who visits is very impressed as soon as they walk in with the warmth through the house."

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.
