This is a major addition to an existing house in a verdant Adelaide Hillsvalley, subject to heritage control. A new living area large enough for an extended family gathering is located at the north end of the house which allows it winter sunshine and long views down an English-style garden. Meanwhile a new bedroom suite with a balcony is sited upstairs, for the same views and sunshine. The living areas open out onto a large elevated deck and swimming pool area. The northern roof slopes are loaded with solar power and water heating gear.
