About eHaus

eHaus – a brand of ecoBuild Developments Ltd (eDL) was established in 2010 by Baden & Glenda Brown and Jon Iliffe with the dream of creating a New Zealand owned and operated specialist design and construction company using PassivHaus build & design principles.

Often referred to as the ‘world’s leading standard in energy efficient design” the German engineering intelligence behind PassivHaus encompasses unprecedented Health, Comfort, Energy efficiency benefits and high quality buildings.
Baden a New Zealand Master Builder of 20+ years and Jon a HND Mech Prod Engineer from Rolls Royce motor cars in the UK, realised the opportunity this revolutionary way of building PassivHaus bought to the New Zealand building industry and the incredible benefits these spaces offered.
That same year they both studied and qualified in the use of the German PassivHaus software through the Auckland Unitec facility. The software, at the very heart of the build, models the performance of how the building will perform before a single stake is put in the ground. They then invested 100’s of hours translating PassivHaus to the New Zealand conditions, applying the building science to the 18 climate zones for both the North and South Islands.
Together with Glenda, a member of the NZ Institute of Directors and an accredited business mentor who has 30+ years working in Chartered Accountant offices, has seen the business grow a nationwide team of qualified PassivHaus designers and tradespeople. eHaus is now recognised as award winning, and the leading player in the New Zealand PassivHaus market.

We live PassivHaus … it’s what we do.

Our eHaus builds


This Award Winning home located on a beautiful rural lifestyle block north of Hamilton has four bedrooms, two bathrooms, two large north facing living areas with plenty of indoor outdoor flow, and a double garage.

A large covered outdoor living area is assessed from both the living areas. Contemporary exterior finishes of black brick and cedar cladding, with the timber and black detail carrying through into the interior finishing, especially in the beautiful designer kitchen and scullery.

This house also showcases extensive interior joinery in living, dining, laundry areas. With many energy efficiency features such as the high performance German Engineered window and door joinery, solar PV system, Ventilation system with heat exchanger, Heat-pump domestic hot water system, and airtight construction, which enable it to perform to such a high standard. This home was extensively computer modelled using the local climate data prior to construction to ensure thermal performance of every detail.
Previously the Waikato expoHaus, the home is now a private family home and no longer available for open viewings. If you are wanting to experience an eHaus first hand check out the eHaus website for open construction days or client open days.
