eHaus Euro - Passive House Low Energy Standard - Non Certified

Designed by Jessica Eyres of Hiberna this holiday house was build as a base for its owners to explore the outdoors with their young family. They wanted something minimal, industrial, and inspired by the South Island high country huts, great connection to the outdoors, plenty of storage and overflow sleeping space for family and friends. The brief also needed to consider hard-wearing durable finishes, a big mud room for wet and muddy gear and a warm comfortable efficient space. Jessica worked with eHaus to design and build this simple yet beautiful home set in the breathe taking backdrop in Twizel. This energy efficient house has outstanding performance with feedback from guests “it was snowing and cold and we didn’t even need to light the fire” This home has featured on the front cover of the international Passive House Plus Magazine  and also New Zealand House and Garden November 2017 edition

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.
