The brief was to maintain the existing footprint and utilise part of the existing structure, and to create a contemporary building that embraces and complements the natural setting with state-of-the-art, energy-saving installations. Maximising the Sydney Harbour and nature reserve views was paramount, with careful consideration to the aspect of the building. The house is in a flame zone, so thorough planning of the home’s protection was undertaken with a fire consultant. The clients were very interested in keeping the house as green and thermally efficient as possible. They fulfilled their dream in several ways, including high levels of thermal insulation, and all windows and doors are double glazed.  Solar panels are connected to battery backup with remote monitoring. The house has been wired for smart home installation, which includes automated blinds, curtains and fire shutters. Sensors in selected areas provide low-level lighting at night. Dimmable and automated lights can be remotely controlled via a phone app. LED lighting is used throughout the house. Fire shutters are externally fitted to windows that can be used as sun-shading devices, and also control winter heat loss.  A 20,000-litre water storage tank is plumbed for garden irrigation, laundry and toilets.  It is a worthy winner of the 2020 Excellence in Energy Efficiency Awards.
