Taranaki ThornburyeHaus Euro, Certified, Passive House Classic

Discover

These clients came to eHaus with clearly-thought through requirements: simplicity without compromise on performance or construction. They wanted a certified Passive House with quality, low maintenance and durable construction. While energy efficiency was important, other performance standards were required. The house needed to be readily secured plus resilient to high winds, storms and earthquakes.
Air quality and environmental considerations were also important with low VOC and natural materials being required.

The clients understood the trade off between size, budget and quality and their instructions to the designer were clear: stay within the budget, shrink the house rather than skimp on quality.

The eHaus design team delivered a Certified Passive House with two bedrooms, an office, two bathrooms, a spacious laundry and a reception area, all within a TFA of 121 m2 plus a double garage.
