the mail room and was initially only at ground floor level. To the first floor were the quarters, accessed from the private entrance and stairs to the northeast corner of the building. These spaces were strung along an L-shaped corridor, which ended at a south-facing window overlooking the roof of the telephone exchange below. At an unknown date, but prior to the major building works of 1941, a stair was constructed within the loggia facing to Palmerin Street. In 1941, a sizeable two-level extension was constructed adjoining the building's east elevation. The addition was as deep again as the original building and doubled the Grafton Street elevation. The building was constructed of rendered brick and roofed with terracotta tile. The 1941 works are further described below under "Existing condition and intactness". Internally, the ground floor retail space exhibits elements of the original interior scheme as well as the 1941 finishes. There are a pair of polished timber framed glazed entrance doors with a multi-paned transom above, set in to a door frame comprising "moderne" column clusters. The walls have a dado of polished smooth timber ply and the windows retain their original double hung timber framed sash form to the Grafton Street elevation. The unused doors to the centre of the Palmerin Street elevation have a similar toplight form and the framing of the adjacent windows has been altered to a "moderne" profile. The original cast iron columns and v-jointed painted timber ceiling is visible within the space and modern suspended pendant lighting has been installed. Air conditioning services have been suspended below the ceiling and are therefore fully visible within the space. Counter forms and merchandising equipment conform to a standard Australia Post suite of finishes. There is an automatic sliding door to the post office box area, contained within the loggia to Grafton Street and extending into the 1941 wing. The archway at the east end wall of the loggia has been infilled with sandstone and the posting boxes in stalled in front. An original archway leads into the post office box area from Grafton Street. The building has two levels, comprising: Structural frame: cavity walled brick, honed and split-faced sandstone sheathing. Concrete pier footings. Some steel framing for the windows (in the annexe). Timber window framing elsewhere External walls: cavity walled brick, sandstone sheathing, some timber in the additions Internal walls: hard plaster over brick, later walling
