We were the designer, builder, Passive House consultant and client for this project so it has a special place in our hearts. It is also the first strawbale certified Passive House outside of Europe. We chose strawbale and timber frame because of the very low carbon footprint of these materials.
The house is also one of only a couple of Passive House Plus projects in NZ. This means that the house generates as much energy as it uses.
We had a lot of fun with the interiors with this project. More than 10 years of dreaming!
We tried to use as many natural and reclaimed materials and fit out items as possible.
A Homestar rating is underway.
Many thanks to Alpine Image Co for the beautiful photos.
