Otago – St Clair Dunedin
About
Certified PassivHaus Classic
This amazing home sits south west over the coastal view. The architects had to solve the issue of being able to enjoy the vista while enabling some shelter from the prevailing winds. Super insulation was used along with Triple argon filled low-E coated glazing necessary for the climate this far south. European windows by ecoWindows in wood and aluminium also feature. This grid tied photo-voltiaic home is perfect for this progressive family, often generating more energy than it uses.

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.
