The Kanuka house is inspired by the surrounding natural environment. The use of locally sourced materials, such as the Southland maple-beech ceiling, enhance the home’s connection to nature and brings a natural, warm and textured element to the home. Wildlife-friendly planting helps draw birdsong into the home, creating a harmonious connection between indoors and outdoors.
The home incorporates many principles of passive design through its response to the local climate and site conditions. The clients were keen to maximise thermal efficiency and minimise environmental impact where possible. This was achieved through a process of careful planning during the design and detail phases, and a clear communication path with the contractor on site. The result is a home that is well insulated, air tight and remains at a consistent temperature all year round. Natural wool insulation was installed in dual layers to help minimise thermal bridging, whilst celebrating the clients’ proud history as Central Otago sheep farmers. A blower door test was also conducted during the construction phase to quantify the home's airtightness, achieving an impressive rating of 1.16 air changes per hour (ACH). This accomplishment is noteworthy, considering that the Passive House standard mandates a rating of 0.6 ACH.
