All buildings have been designed to maximise comfort by using passive solar energy, cross ventilation, thermal and acoustic insulation, wood heaters and fans. Construction materials have been chosen to compliment the surrounds as well as for their practical application. The use of strong chemicals for termite protection has been avoided where possible by using cypress timbers, termite mesh and practical design. Unfortunately it was necessary to clear heavily wooded areas to position buildings safely here at Heaven, but all timber has been used onsite for landscaping, fencing, rough construction, or future firewood. Reforestation of these areas has been a priority. Underground water storage has been incorporated into the design of the buildings and has resulted in the storage capacity of 382,500 litres (85,000 gallons) of fresh rainwater. The use of two onsite home sewerage systems has been necessary because of terrain restraints, but all grey water is used in reforestation of the native bushland and gardens and is of great benefit in keeping our surrounds lush and lively. Heaven in the Hills takes total responsibility for the production of its own electricity and is not connected to the electrical grid. The system is based on renewable energy sourced from solar and wind generation. Energy is stored in 48 gel cell batteries and converted to 240 volts by an inverter. This enables the use of conventional appliances throughout the property. Gas and wood are used for heating. However, behind the scenes much thought and planning has resulted in efficient usage of power especially in areas such as gravity fed water, low wattage light bulbs and the above design features, maximising light and temperature control. Heaven in the Hills and the surrounding area is teaming with wildlife and is home to many wallabies, birds, possums and the like. You don
