Sitting on a 1-acre property at the edge of Mundaring townsite, this house is a sophisticated response to its setting. The building forms a simple L-shape in plan, with a 2m wide Jarrah deck verandah running along the inside edge, focusing the house onto the social hub: a central terrace and lawn area. The living spaces are laid out within one large volume that is bookended by a sophisticated natural oak kitchen on one end and a recycled brick fireplace (with pellet stove insert) on the other. The room has large sliding doors facing north, creating a seamless indoor/outdoor connection. The highlight windows above the doors let light deep into the room, allowing for passive solar heating in winter using the polished concrete floor as thermal mass. Windows on all sides of this room allow for cross-ventilation, and ceiling fans throughout provide air movement for thermal comfort. The house has achieved a NatHERS rating of 7 stars, and has no mechanical air conditioning. The house includes three large bedrooms, two bathrooms, a generous laundry, a large office/guest bedroom, and an activity room for the children directly adjacent to their bedrooms transforming what would otherwise be wasted hallway space. The building is constructed using a slab on grade foundation, double brick end walls, highly insulated timber frame construction for walls and roof structure, and Colorbond roofing.
