eHaus Euro - Passive House Classic

This large 370m² family home located in rural Waikato, has five bedrooms, 3 generous living areas, three bathrooms, and a triple garage. The main hub of the home with kitchen, dining and living areas, opens onto two separate outdoor spaces, one an intimate alfresco dining area and the other having an outlook onto the pool and children's play area.

The exterior is clad in a mixture of Cedar and Schist stonework, and features recessed window installation, resulting in an attractive detailed aesthetic.

European Larch - Aluminium window and door joinery gives beautiful warmth to the interior, while also ensuring ultra high thermal performance and airtightness.

Both shading and glazing on the north facing facade have been cleverly designed to meet solar gains vs heat loss balance, resulting in a home with extensive indoor - outdoor connection with the beautiful landscape.

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/
