Sustainable House Day is this Sunday – September 15, and provides a great opportunity to visit some of Australia’s leading green homes. Local homes that are environmentally friendly, cheaper to run and more comfortable to live in.

Across NSW more than 50 houses are open for you to explore and learn from. In the Eurobodalla, open houses are located at Dignams Creek, Moruya, Malua Bay and Broulee. Each is different, but all provide you the opportunity to inspect firsthand home designed with sustainability in mind plus the opportunity to talk to the owners and receive that valuable, real-world, unbiased advice.

Kurrajong Hill at Dignams Creek

Between Bega and Narooma, the home of Fiona Kotvojs and Alan Burdon’s will be open.

Fiona and Alan, built their home on Fiona’s family farm which has always been off-grid, without town water supply, and is likely to stay that way.

This two-storey home built with views over the National Park, is a solar passive, completely self-sufficient in terms of power (solar) and water supply (rain).

The internal temperature is maintained through a combination of building materials (straw bale and rammed earth), window design, sunroom, ventilation and a masonry heater – a traditional European wood heater that is more efficient and produces less emissions than other forms of wood heating available in Australia.

Water is heated with an evacuated tube solar hot water system, and a backup wood-fired Rayburn stove (also used for cooking).

With a 250,000L tank, water use has been designed to maximise efficiency, with composting toilets and reusing greywater through the orchard.

Located in an area subject to ember attack, a number of features to minimise the threat from bish fire are included in the house and garden design.

“There is often a perception that living in a sustainable house often means doing without,” Fiona says, “But this need not be the case.”

“Most days we can run everything we want, including two chest freezers, a dishwasher and, in summer, a fruit drier.

“For the grey days when there just isn’t enough power, we plan our usage more carefully and have a back-up generator when needed. And at the end of this, there is no power bill.”

Open 10 am to 4 pm, entry by donation for Cobargo RFS or Oxfam Australia.

The gardens are designed to be aesthetically pleasing but also functional and provide habitat and food for native wildlife and insects. There is a range of fruit and nut trees, chickens, worm farm and compost.

Paul designed this home for his family to showcase how specifying the correct materials can result in a sustainable house at no extra cost.

The house features blockwork walls and an exposed concrete floor for thermal mass. A lot of work has been done to improve indoor air quality, with virtually no treated timber internally and low or zero VOC paints and sealers throughout.

The stainless-steel kitchen eliminated formaldehyde off-gasses normally associated with kitchen cabinets is easy to clean and reduces bacterial build-up.
