Passive Solar Design is supported by double glazed windows created by a local crafsman using western red cedar and Pilkinton Glass modules. The concrete slab has black state tiles in full winter sun and the mud brick (mass) walls are insulated by a rear laundry and bathroom skillion. \"The house extension is unquestionably modern, yet sympathetic to the existing cottage. [...] A beautiful sense of spaciousness was created by timber-lined ceiling which follows the line of the hipped roof, and by the windows on the corner to the east. This eastern window is protected by a shutter. The western verandah was continued around the corner along the northern side, terminating at the small sun-sewing room. The openings to the north, wich are under this new verandah, were enlarged and an open-plan kitchen-dining-living area connects the existing house to the outside.\" Choice Books \"Warm House Cool House\", 1995, Nick Hollo, Inspirational designs for low-energy housing
