This home is built on 3 levels nestling well into the natural surroundings. With a garage and workshop downstairs, 3 bedrooms above that are connected to the open plan kitchen dining space. There is a private deck at the rear of the property giving great indoor outdoor flow. Just a 1kW panel heater is sufficient to keep the home warm in winter and the solar PV system ensures minimum running costs throughout the year.
