Off-grid living in the Adelaide Hills
With its own electricity and water supply this Adelaide Hills home demonstrates modern off-grid living.
The self-sufficient contemporary home sits on 76 hilltop acres with 360 degree views to McLaren Vale and the coast.
Energy efficiency and healthy house principles were essential to the owners, creating a place that’s in harmony with the environment.
The house features good passive solar design including reverse brick veneer construction to increase thermal mass within the home. The property was not connected to electricity or water, so has an off-grid solar power system and independent rainwater and borewater supply.

SUSTAINABLE FEATURES
Hot Water
Cromagin Solar Hotwater with instantaneous LPG backup.
Renewable energy
3.7 kW solar off-grid power system, maintained by Solar Depot.
Water saving
There is no mains water. Two rainwater tanks collect 151,000 litres of rain water.
The wet collection system has been fitted with first flush diverters and drainage points to keep the water free from roof debris.
All greywater and blackwater is sent to a traditional 44 metre long soakage pit, and trees are planted to take advantage of the moisture.
Water is pumped to the house and garden via a pressure pump and pressure tank.
Passive design/heating and cooling
There is R2 insulation in all internal walls, and exposed stone is used as thermal mass.
The roof is light coloured Colour Bond, with R 3.8 insulation and sisalation.
Condor roof ventilators assist the indoor temperatures in both summer and winter.
There are deciduous vines in the courtyard. Full-length exterior blinds keep the house cool while allowing occupants to enjoy western and eastern views.
Active heating and cooling
The home is heated by a wood fire, collected from fallen timber on the property. An evaporative cooler is used during extended hot periods.
Building materials
The construction of the house is reverse brick veneer, timber frame, R2 insulation, sisalation with external colorbond cladding, which is light in colour to reflect the heat.
Windows and glazing
The home has double glazing throughout, with insulated curtains, and curtains hung from the ceiling to eliminate the need for pelmets and exterior café blinds to shade house in summer.
Lighting
Compact fluorescent and LED lights.
Paints, finishes and floor coverings
Slab construction with waffle pod, solid timber used in main living rooms and Marmoleum in bedrooms/studios.
