Touted as a one-of-a-kind property, with a swag of environmentally-friendly features, the house sat on the market for four months.

Despite being listed with a number of real estate agents, it took 153 days to sell, much longer than the average of 50 days for Bathurst house sales, according to RP Data.

Last month, Richardson and Wrench Bathurst principal Peter Ison, who had the house listed for sale, slammed council for the “waste of ratepayers’ money”.

Built in 2011 at a cost of $350,000, the house was put on the market on May 1 for $499,000.

“There are generally two reasons properties don’t sell – a lack of marketing or it’s too expensive,” Mr Ison said at the time.

“If buyers were keen to have sustainable homes, they would have built one themselves.”

Not long after the Western Advocate reported the lack of buyer interest, council reduced the price by $59,000 to $440,000 – an 11.8 per cent drop.

Raine and Horne Bathurst was another real estate agency to list the house, and director Michelle Mackay said when it first hit the market it was very overpriced.

“It was way too high, we went in at $440,000,” she said of her sale price estimate.

She added that council was right to cut its losses and drop the price for the property.

“They lost money on it. There were no tenants in there,” she said.

As the house is under contract, the sale price can not be released to the public until contracts have been exchanged.

The sustainable lifestyle was built as a showcase for a range of sustainable construction techniques, materials and design features.

The home incorporates passive design techniques which include the house’s orientation, zones, thermal mass, shading, insulation, ventilation and glazing.

It has a 50,000-litre underground rainwater tank, as well as a grey water treatment system and double glazed windows. All plumbing fixtures meet a five-star standard of water efficiency.
