The house is named the Tree House due to his stunning nature views and wooden structure. Its previous owner had bought the unique house from the estate of the late Australian actor in 2008, the Daily Mail reported.
The house has contemporary rooms, vast seating areas and a Zen-like garden. Built in 1951, the stunning hideaway has two bedrooms, two bathrooms and a modern kitchen.
