eHaus Euro - Certified Passive House Classic
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.

About the
Professional
At eHaus, we live like efficiency is our point, and intelligent construction our norm. We live like our environment is a privilege and protecting it our responsibility. We live like New Zealanders are our passion, and ingenuity is our response.
eHaus was established in 2010 by Jon Iliffe and Baden & Glenda Brown with the dream of creating a New Zealand owned and operated specialist design and construction company using PassivHaus build and design principles.
Jon, a Mechanical Production Engineer from Rolls Royce Motors, arrived in New Zealand and looking to build a family home went seeking out alternative options and found the PassivHaus way.
Baden, a master builder of 20 years, disillusioned with the poor performance of the high-end homes he was building for clients, also was seeking other options, and discovered PassivHaus. Together, with Jon and Glenda - Financial director, eHaus was formed.
Our eHaus team is made up of some of the country's best Passive House builders, architects and designers who are redefining the way kiwis live, one home at a time. Our team of professionals work together to see your dreams come to reality.
Today eHaus is recognised as award winning and New Zealand leaders in PassivHaus design and construction. Find out more about eHaus and our teams here: https://ehaus.co.nz/
