Place 1: Chester Road, Wondecla (Southern End of Atherton Tablelands)
Our house is a two storey two bedroom home built on the bank of a small creek in a 1.79 ha forested block.It is off the ground on mostly steel stumps and is constructed of recycled timber and timber milled by John as the owner/builder. Read More
The house is clad in Weathertex which is a board derived from wood residues, and is fire and termite resistant.
Electricity Is supplied by a 1.3 kw stand alone PV system which was sourced mostly second-hand and installed by John. There are also some new panels purchased under the Green loan scheme. This supports a 12v fridge/freezer, a 240v 1601 upright freezer, laptop, TV, sound equipment,
washing machine etc with the aid of a 1500w inverter. Lighting is 12v with mostly LED globes with still a couple of dichroic down lights in low use situations.
Water is trapped on a 90sq mt shed roof and fed into 3 water tanks for a total capacity of 7300 gallons, 2 of these tanks are directly plumbed into the house.
Toilet is a Naturloo com posting unit, which could probably benefit from the installation of a heater, however, our power system is not large enough to support this.
Grey water is caught in a small concrete tank and pumped out and used for irrigation of the native vegetation.
Our home has been built with coolness in the hot weather our main priority, so with wide eaves, high ceilings and good cross flow ventilation we have achieved this and have no fans or air conditioners.
For the relatively short cold season we have a wood heater and abundant source of firewood on the block.

Place 3: Atoll Close, Port Douglas
I live in a solar powered townhouse in Port Douglas. The complex is retrofitted with 2 grid connect systems and the community solar that powers our pool pump. All systems are proven to be giving positive investment value and paid off within two and a half years. I also have a solar hot water system and solar oven. Read More
There is a roof garden over the carport with a rainwater tank behind my carport.
As a body corporate community, we have a strong sense of sustainability, and are growing more fruits and veges in our organic community garden. There is talk of a community water tank as well.
I have 40 years’ experience in renewable energy systems including motor vehicle energy systems and will enjoy sharing this on Sustainable House Day.
