Whitehall
About
This thoughtfully designed eHaus is Marlborough’s first certified Passive House.
Built to perform, the home features 190mm thick walls, triple-glazed windows, and exceptional airtightness, delivering year-round comfort and remarkably low energy use.
Inside, the spacious layout includes three bedrooms, with a generous master suite complete with walk-in robe and ensuite. An open-plan kitchen and living area connects to a separate media room and office, offering both space to entertain and quiet corners to retreat. A covered deck extends the living outdoors which is ideal for Marlborough’s long summers.
Designed and built for a couple downsizing from a draughty 1920s bungalow, this home will provide a far more comfortable retirement than their previous home.
You can read more about the couple and their decision to build a Passive House here.

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.
