Key Green Features

Green Roof

This is a Terradome construction which provides year-round comfort without the need for heating or cooling. The north facing facade was finished in a multicoat polymer system to aid in insulation and the upstairs windows are double glazed and fire rated. This property has been built to blend with the environment and provide a sustainable residence for generations to come.

Native Landscaping

The gardens are mainly native plants and trees suited to this environment and require little ongoing care.

Rainwater Harvesting

Water is sourced from an underground bore that provides ample water supply that is of very good quailty.

Biowaste Management

Waste is managed through a biolytic septic system (worm based) which works very well with no odour and no ongoing maintenance.

Eco-Friendly Materials

Earth / Soil

Where was this used? On the roof and surrounding the house other than the North facing facade.

Energy Sources

solar

Output: 1kw

Year installed: 2000

This property faces due North and has no shadowing issues. It is therefore a perfect candidate for solar. The property is connected to the grid and uses very little power. The small solar system in place is now redundant.
