eHaus Euro - Certified Passive House Classic
It’s remarkable how much fits inside this two-story 151 m2 home for an extended and expanding family. The clients wanted a functional and compact home, a place that was both dignified and comfortable. It also includes a self-contained flat, gym, library and 3.5 bathrooms
“Without a doubt the most comfortable house we’ve ever lived in, year-round and without having to burn power to make it that way, which is awesome”

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/
