Super-efficient space layout, no hallways and no wasted space, combined with energy efficient solutions and beautiful timber features.
The owners of this home were driven to build due to the unknowns of purchasing an existing home in post-quake Christchurch. As creative people, and experienced in building, they wanted to be hands-on and knew that it would not be possible to get what they wanted with a volume building company. Over the course of many conversations with their close friend, and eventual builder, Aaron Stewart they started to put together a vision for a house where the effort and resources is put into the design and quality of the building materials rather than the size of the house. They developed a sort of mantra of ‘there must be a better way, which drove them to seek out smarter, more effective, efficient materials and ideas. They wanted a unique design that also felt instantly welcoming and homely, while also feeling a little like mountain retreat rather than bungalow.
They liked the idea of a Passive House but knew that their budget would not stretch that far so they decided to downsize slightly to allow increases in thermal efficiency while staying within the budget.
Aaron Stewart introduced them to architectural designer Susanne Schade who instantly understood the vision for building a smaller, more efficient home with as little wasted space as possible and a very low maintenance exterior.
The house was built in 7 months to a Passive House standard using conventional timber framing made up of 140m wide LVL studs to create a thicker pocket for more insulation. There is a 45mm insulated service cavity and airtight wraps on the interior and exterior keep help maintain the efficiency of the insulation. Cladding is corrugated Flaxpod Colorsteel.
The roof is corrugated iron over purlins, roof underlay, and a scissor truss (skillion roof) insulated with 210 mm thick Knauf insulation segments, R-Value 5.2.
The floor construction is particleboard over floor joists, with insulation of two layers of Knauf 75 mm underfloor insulation rolls with wind wash barrier, R-Value 1.8 each, over bearers and piles.
The benefit of the chosen construction method is that the house is very air tight and very well insulated, hence the warmth will stay within the house and the energy consumption will be very low. The house comprises of a heat recovery ventilation system (Lunos System) which provides fresh and healthy air throughout the home.
