The mountain-view- facing box has an ideal roof surface on which a 6.7KW solar system could be installed for power generation. The sun-facing box was designed to serve as the sleeping quarters, to maximise comfort at night usting the optimal passive thermal performance during the day. Outdoor watering system - Hand watering of mostly native garden.Fittings - 4 star Toilet, 3 star shower head.Water Harvesting - 22,000L of rainwater storage collected from entire 110sqm roof, feeding whole house.Power is provided by 23 solar panels on the living room roof, with an output of 6.8 kilowatts, that is stored in 13.8 kilowatt hour battery.Appliances - Air sourced heat pump hot water system, 3.5Kw Ilve Oven, 450L LG Fridge with 4.5 star rating.

The solution was to split the house into two steeply pitched skillion-roofed boxes, oriented in opposite directions, and performing in different ways (see below). To capture views of the mountains to the south, the open-plan kitchen, living and dining rooms would need to turn their back on the sun, which is not ideal for passive solar performance.
