Timber, wall-mounted lockers are to be found either side of the wide doorway that leads into the back section of the building. Panelled timber doors with fretwork fanlights are opposite each other at the back of the hall. They each lead into large rooms, formerly the wards of the sanatorium, now subdivided into four small rooms. These rooms do not have full height partitions and the space of the wards is discernible. The raked ceiling is lined with tongue-and-groove with two horizontal bracing members running across the room at the same level as the top of the walls. Light fittings and switches are suspended from these members. The northern face of the ceiling has a centrally located, timber framed, fixed glass skylight whilst on the western and eastern walls respectively, there are small corrugated fibreglass panels that also let in light. A section of rendered brick provides evidence of the chimney once located in the eastern ward. The chimney remains in the western ward, however, it has been blocked up and there is no fireplace. Evidence of windows is visible along the northern walls of both wards. The side extensions are accessed via partially enclosed passageways at the back of the building. Between the wards and these passageways are lean-to additions with skillion roofs that each contain a further two rooms. At the western end of the building there is also a timber toilet block with terrazzo floors attached at the northern side of the passageway. The western extension contains four equal sized rooms, with three-quarter height, fibrous-cement partitions and lino floors, the eastern extension is divided into five small rooms. The perimeter walls have multi-paned, coloured glass sliding windows and timber sills with tongue and groove lining below. Many of the rooms are furnished with cast iron beds from the sanatorium. Original doors are located in the wall between the former ward and the eastern extension. The kitchen and former maids' quarters are located at the end of the hallway in a small building semi-detached from the main building. There is a small north-facing verandah at the back of the kitchen with stairs to the garden that together with an adjacent bedroom forms an extension to the original kitchen. The kitchen building is single skin timber with exposed cross bracing, a hipped corrugated iron roof and a brick chimney on the western wall. The extension is clad with horizontal weatherboards and the verandah has a dowel balustrade and simple valance.
