The Shotover Passive House was designed to suit a family in search of a comfortable, energy efficient permanent home in one of Queenstown’s newest suburbs. The original brief was for a simple but dramatic design that would overlook the park to the north of the house and contract with the more conservative surrounding dwellings. The form became simpler during the design process, while the non-thermal façade elements (especially to the north) gained depth and complexity to provide shading. From the outset, the design was always intended to be built using structural insulated panels, and a small amount of steelwork to facilitate speedy construction and an open plan design.
