Thalia Haven, East Coast Tasmania, is a luxury off-the-grid stone residence with electric power from photovoltaic cells, a wind turbine, and solar water heating panels that support the full range of modern cooking and washing appliances. Double-glazed, recycled, hardwood timber framed windows and doors capture the sun for passive solar space heating, while opening across a sweeping seascape to the mountains of Freycinet Peninsula and Schouten Island on the horizon. Supplementary gas heating is available, though this is seldom, if ever, required. Feature stone walls and functional stone fireplaces to the living room and kitchen/dining spaces provide character and solidity, and imbue added ambience to the interiors. Water supply is rainwater harvested from the roofs and stored in an underground tank. The stone walls and dark limestone flooring are well insulated and provide thermal mass for heat retention and moderation of interior temperatures.
