When architect Paul O’Reilly of the Australian architectural practice archterra was asked by his mother to design a modern farmhouse, he delivered a handsome dwelling that not only takes inspiration from traditional barn architecture, but also deftly addresses the region’s climatic extremes with its site-specific, energy-efficient build.
Aptly named the Farm House, the roughly 2,000-square-foot abode features a gabled roofline, a veranda and timber cladding to mimic traditional barns, while the interior is decidedly contemporary and dressed in natural materials, including rammed earth and oiled timber cladding. Moreover, the home is energy-efficient, taking cues from passive solar principles and drawing power from a 2.5-kilowatt solar photovoltaic array.
Located on a grassy paddock on a working cattle farm near Margaret River, the Farm House is a two-bedroom, two-bathroom abode that places the sleeping areas toward the south and the open-plan living areas to the north. Large outdoor decks open off of the two bedrooms and the living area toward the east.
“Primary outlook across paddocks to the east and a need to maintain a passive solar orientation to the north generated a T-shaped plan response with the living pavilion orientated to the north, whilst the sleeping areas align east-west,” explained the architecture firm. “Morning sun is moderated on the sleeping pavilion by the traditional veranda to the east whilst a thick rammed earth wall to the west ensures the thermal lag effect of the earth wall keeps internal spaces cool into the early evening.”
The home’s passive solar orientation mitigates unwanted heat gain and permits cooling cross breezes to flow through the home from all directions. In addition to the thermally efficient envelope, the energy efficiency of the Farm House is bolstered by the addition of an evacuated tube solar hot water heater, a solar photovoltaic array, rainwater collection and wastewater treatment systems. Recycled timber and bricks lower the embodied energy of the project as well.
