Sustainable home design is one which allows homes to be environment friendly for a number of years. One of the major problems for any house is the availability of drinking water. Here you can see a beautiful project in Perth which makes use of water through innovative methods. These include rain water, water efficient gardens and grey water. The description of how this water is to be used has been provided in this video. Not only is ground water being used, but it is also being replenished. The sustainable home dream also includes use of solar power. Low energy lighting, sustainable landscaping and energy efficient appliances are being used here.
