Greycliffe House Greycliffe House is a two-storey "Marine Villa" of sandstone construction with steeply sloped gabled roof covered with Marseilles pattern terracotta tiles, the roof originally was timber shingled. It was designed in the Victorian Gothic Revival manner by architect J. F. Hilly for the owner John Reeve and completed in 1851. Hilly probably based his scheme on a pattern book design as he did for many other similar houses at that time. The result is very picturesque, well suited to its woodland harbourside and hillside setting. As viewed from the harbour it is very similar to its original appearance although its original design intent has been somewhat altered by later alterations and additions at its rear. The original design consisted of a two-storey villa for the main living quarters with bedrooms above and a single storey kitchen and scullery at the rear. Nearby was a detached attic storey sandstone coach house and stables with staff quarters above. This arrangement is clearly shown on a map of the area with the house served by the present access road. This plan also shows the fencing that separated the property from the rest of the Vaucluse estate and the adjoining Carrara estate. Following a major fire in 1897 that severely damaged the house, it was rebuilt and was altered and added to providing more staff accommodation. The owner, Fitzwilliam Wentworth, added another storey to the kitchen wing in a similar style to the main house. During its conversion after 1914
