Located in Bundeena, a beachside village 25km south of Sydney in the heart of the Royal National Park. Conceived as a treehouse with open platforms nestled amongst the tree canopies, this home is elevated on steel columns to minimise disturbance to the rock outcrops and vegetation and to reach for sunlight and views of the beach and water beyond. Traditional beachside holiday-home materials are employed throughout the project with steel framing, cement sheet (Barestone) external walls, metal roofing, plywood internal linings and timber floors. The simplicity of the materials is offset by the precision of the construction and detailing.
