kitchen on the rear veranda, the demolition of the garage, bathroom annex and rear skillion and the reconstruction of the current rear addition. It also appears that the cottage was used in association with fruit and vegetable gardens for the estate as these are shown fenced and adjoining the cottage, and afterwards in Trust and NPWS ownership it has served as quarters for park rangers. Despite various works having been undertaken, the building is in quite poor condition and requires substantial upgrade. In particular drainage around the building and termites are causing substantial damage. The Margaret Harper Wing Built in 1939 as a hospital wing for Greycliffe in its role as a Tresillian House it was designed by architect Gilbert Hughes to provide private ward accommodation for nursing mothers and student nursing staff. The asymmetrical planned building of rendered brickwork with gabled terracotta tiled roof reflects the character of Greycliffe and was originally physically connected. The design has been referred to as being in the Interwar Mediterranean style however its Tudor Gothic Revival roof, chimneys and wall details with its colonial Georgian windows and Spanish colonial arcades possibly suggest the emphasis may be towards Neo Colonial Gothic Revival style.

Some significant moveable heritage is associated with the Tresillian period of occupation of the site including a number of baby bassinets. From time to time birth and health certificates are also donated to PWG by people who were admitted to the centre. These are held on site.

The two northern gun pits and connecting trenches are open but the one southern gun pit is filled with sand and has been turfed over. The fortification also consists of a north-south tunnel with a western branch down a stairway to the original magazine. A small room, probably intended as a "stand to" area for gunners is situated at the north end of the tunnel wall. At the south, the tunnel branches southeasterly to a stair connecting to the filled gun pit and
