Manawatu Ranfurly Non-certified, eHaus Euro, PHI Low Energy


Imagine opening your front door to an uninterrupted view of rolling rural hills in the background and a contemporary outdoor lounge and pool area in the foreground. For these clients, the brief was simple: a home that took advantage of the view without being swept away by the mighty winds that flood in from all directions. For the eHaus Manawatu team, the design challenge was doing the architectural plans by 242am Architects Ltd justice. A simplistic layout and intricate design coupled with clever detailing elevate this long property into impressive proportions. Multiple exterior claddings, including Otago schist and vertical shiplap cedar, complement the natural surroundings, while 6mm negative detailing for the skirting and architraves on the interior walls keep hallways flush and modern. These incredibly patient clients were trusting of our team to make the right calls in terms of detailing and material choice and, thanks to their commitment to the PassivHaus performance criteria, are now enjoying the benefits of the journey.

This home is the winner of nine awards in the National & Regional Registered Master Builder 2021 House of the Year Competition, which is an absolute testament to our team's building excellence, architectural, interior and landscaping design.

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.
