There are also a few closeups of the stone staircase that leads to the water, as Holden and Jones run up them. Sadly for us, the rest of the scenes supposedly filmed inside the house were actually studio sets back at 20th Century Fox.
Built in 1953, the building was only a couple of years old when the film crew captured its exterior and according to a commentator on Gwulo.com, the film stars also stayed here when they were filming - I imagine it would have just been for a couple of nights maximum whilst all the Deepwater Bay shots were completed.
It's unclear when the building was demolished but the rocky promontory it sat on is still intact, however, it now houses a small luxury development called 34 Island Road. Additionally, the area on the seaward side has been extended to facilitate the construction of the Seaview Promenade.
