Text description provided by the architects. The shape of the house’s courtyard is driven by the constant winds of Wellington and the desire to protect an area of outdoor space to open up to it. The house is completely empty and very insulated from all the exterior walls except for the north facade which lets in the winter sun on a concrete slab insulated for passive solar heating. All rooms in the house open onto a central courtyard which provides daylight and natural ventilation.
The house is located on a natural thermally broken concrete slab and has a thicker wall frame to increase the levels of thermal insulation. The empty exterior faces of the house are often covered with economical and fireproof fiber-cement panels while the court-facing walls are covered with locally sourced, untreated Heart Macrocarpa. Exterior screens/roofs made of airtight corrugated polycarbonate panels protect from the wind while still allowing the sun into the garden.
The windows are in powder-coated aluminum with clear double glazed units in all directions. Opening the alcove of the bathroom provides easy ventilation of steam. Glazing turns north and west for winter sun to warm the house. Natural ventilation eliminates the need for artificial cooling as all rooms of the house have large doors to the sheltered patio.
In winter, the living room and bedroom concrete slabs receive plenty of direct sunlight which is captured by the high levels of insulation in the slab. There is a very small wood burning fireplace in the living room that can be used as a stove in winter. Hot water is supplied through an instantaneous gas system located one meter from the plumbing fixtures it serves. The house uses low energy LED lighting with ceramic shades by the architects.
