About Oakden

This two-year-old house was designed to meet needs of a couple who have ‘downsized’. Their goal was to design and build a house that met their needs without excess, but with a spacious and light feel. Designed by Mark and Jon from GoodHouse to be energy- and water-efficient, this home is highly insulated and airtight (Pressure test achieved 5 ACH at 50Pa), to keep the home cool in summer and warm in winter with minimal external energy input. Electricity imports average just over 4kWh per day after taking account of on-site generation from a relatively small 2kW PV system. The home is designed to make good use of winter sun in the living area and main bedroom, natural daylight throughout the house and cooling breezes overnight in the the summer.

This home has also incorporated water-wise initiatives including a 22,000L rainwater tank that feeds the whole house and rear garden; drip irrigation for all gardens; water-wise plants and landscape design.
