earlier outbuildings on the site, some of which had been built with Tiffin's original design. The ground floor verandah and first floor balconies were all removed at this time and replaced with cantilevered entrance awnings. These have themselves been taken away since then, so that by default the exterior is relatively close to its original form and its original intentions architecturally. A timber-framed mail room was added and several new doorways were opened up in 1956–7, and the mail room was extended in 1965. Concurrent with these works the internal spaces were upgraded with new timber and glass-panelled partitions, a refurbished public space and the floor and ceiling claddings were also substantially renewed. The original building was 2 storeys high with a 3-storey clock town. The clock tower extended to 5 storeys in 1879. The original fabric of the building includes: Structural frame: Load-bearing solid brick on rendered plinth and footings, timber-framed floor and roof (1866-1885). Reinforced concrete slab to ground floor. External walls: rendered and over-painted brick with cement rendered dressings and rusticated quoins to principal street elevations and clock tower with painted brick to rear elevations. Internal walls: Generally hard plastered brickwork, later plasterboard partitioning. Floor: Ground: reinforced concrete slab; first: timber framed and hardwood boarded. Ceiling: Suspended grid-form acoustic tile, painted beaded timber boards, plasterboard and to first floor, areas of non-original strapped plaster sheet. Roof: Timber framed, hipped form recently re-clad with rust red 'colorbond'; ogee profile cast iron rainwater goods; rendered brick chimneys with moulded caps. Skillion-roofed rear first floor verandah roof finished with rust red "colorbond". Other: timber-framed double-hung sash windows, "french doors", cast iron columns to ground floor public spaces. Condition Internally, wall, ceiling, floor and joinery fabric, including cast iron columns, original to the building and its subsequent nineteenth century stages of development remain throughout, albeit later modified, including the internal planning. Modifications include partitions and false ceilings. Alterations undertaken in 1906, 1925, 1950s and 1960s have impacted on the original albeit-evolved nineteenth century internal and external building components. Timber and brick surfaces throughout have also been overpainted.
