Tim Ross from Architype met the challenge of a long narrow site and district plan setback requirements for this couple relocating to Cambridge who wanted a comfortable, energy-efficient house that would meet their needs as they aged. The layout, structure, services and aesthetics of the building tightly work together to create a simple yet extremely high performing building. Construction was with structurally insulated panels (SIP). A beautifully crafted and designed family home.

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.
