With plans to relocate their existing small house and build a new 3 bedroom house on the same, established location; our clients tasked us with designing an energy efficient, low maintenance home that is suited to its rural environment.
Beginning with the modernist principle of form follows function, the house was designed from the inside out with performance in mind.
The layout is optimised for solar gain, with living spaces facing directly north and utilitarian spaces facing south. The layout also facilitates natural circadian rhythms with the master suite located on the NE corner of the house for morning light, the living spaces facing north for midday light, and the relaxation and entertaining areas facing NW to capture sunset views over the Tararua ranges. The exterior form of a rectangular, metal-clad, gable house references the rural barn vernacular, while also being low maintenance and cost-effective to construct. The pitch of the roof is optimised for solar panels, with eaves sized to let in winter sun but provide adequate shading in warmer months. The engineered pile and bearer foundation elevates the floor off the ground to limit any future flood damage.
To achieve the goal of a high-performance, energy efficient home, the functional design was combined with forward-thinking construction methods.
Structural Insulated Panels (SIPs) replace conventional timber framing and insulation for the floor, walls, and roof. This helps to achieve Passive House style performance by providing extraordinary levels of airtightness and insulation. SIPs are a prefabricated, high-performance, simple, all-in-one alternative to structure/framing, insulation, bracing, and exterior wrap/RAB.
