Taranaki - Oakura 2

eHaus Euro - Passive House Classic - Certified

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."

Our team are very proud of this incredible build.
