Huia house

An energy efficient single level family home that replaced an existing cottage that was removed. Walls are timber framed with weatherboard and baby corrugated steel cladding, and the roof is clad in corrugated steel. Exterior wall framing is 90mm with additional 70x45 horizontals on edge to the inside face to allow for R3.5 polyester insulation. By having these at right-angles, the reduced contact points between the exterior and interior framing will minimise thermal bridging. Exterior joinery is double glazed, thermally broken aluminium framed. Due to the narrow nature of the building platform, and its angled orientation to north, incorporating passive solar design was not feasible and therefore the floor structure is also timber framed. However, high levels of insulation has meant that the house is very energy efficient. Space heating and hot water is supplemented by a Pyroclassic woodburner with wet-back.
