running in an east–west direction is a double loaded corridor, with access to administrative and staff areas on the west including an interview room, office, store rooms, lunchroom, plant and male toilets. To the south, a centrally-positioned passage leads down a few steps to the female toilets, contractors' room and lockers. This section of the building, constructed in reverse hardwood frame has vertical board linings and ceilings and panelled doors, and may correspond to the original 1875 post office. The entire east wing and verandah appears to be an addition built after 1957 and comprises the open mail sorting room and post office box wall; further south, the construction of the service area and loading dock has internalised the former weatherboard exterior. Key elements of the building include: free standing form original composition of a central breakfront gable to Lannercost Street flanked by corner side porches with integrally designed steps and building entries smooth rendered finish and mouldings including the porch columns, capitals moulded string lines and circular gable vents; and wrought iron patterned screens and balustrade to the subfloor areas Condition The original planning of Ingham Post Office comprised twin porches either side of a central breakfronted postal hall. The planning arrangement is assumed to have provided a dual but independent operation of the postal and telegraphic functions. Details of the original internal planning arrangement are not known and further obscured by the subsequent removal and/or concealment of fabric, as well as the additions to the building on the south and east sides. This includes the enlargement and refurbishment of the post shop, the addition of the loading dock, and the extended mailroom wing and verandah. Photographic evidence indicates the east porch was one bay wide and two deep, behind which the transverse gable (located at a lower ridge height that the one currently) included a separate side entry and steps and windows protected by a shingled sunhood. The rear timber reverse-framed section may be associated with the 1875 building. Gvien the changed pattern of use, the building's original design is limited to the street frontage, specifically the projecting north and west gables, west porch and entry, smooth rendered finish and mouldings, and the east verandah and entry to the extent of the first bay. The extended east wing and south service additions demonstrate the ongoing use of the site but have altered/concealed much of the original interior fabric
