site is rectilinear in plan and bound by a chain wire fence. A gravel driveway along the west boundary divides the post office from the neighbouring telephone exchange and provides access to the loading dock subsequently built at the rear of the building. A concrete block hipped roof storage shed has been built in the southwest corner of the site. The post office is near symmetrical on its entry frontage to Queen Street comprising twin corner porches which flank the parapeted postal hall, but is otherwise asymmetrical to the side and rear elevations. It reproduces several of the "Georgian" details of the former quarters (designed by John James Clark), including the pattern of windows. In the manner of smaller Commonwealth-designed post offices of this period, the frontage is parapeted with three tall windows across the postal hall, and with differing windows behind the two entries on either side. Blocks of steps provide access from street level framed by brick piers with rendered capping. The hipped roof is symmetrical about the post office breakfront, but the flanking hip and the figuring of the rear eaves for the main hip are irregular, including from the entrance elevation. The composition plays off a centralising postal hall wing and prominent roof lantern with flanking roof eaves of irregularly varying heights. Overall, it is delineated as an institutional building but retains the small, quasi-residential character that marked post office designs during the 1900-1914 period. Entry to the central retail shop is via the original side porches and steps. The north wing and Young Street entry have been altered by the removal of walls and the installation of a post office box lobby which extends along the length of the elevation. The lobby exits through an opening formed in the west wall and onto a disabled ramp at the rear. Post office boxes have been added to the south porch and the west end of the side south porch infilled to house the air-conditioning plant. Internally, the building has three main sections relating to the front retail shop counter area and the L-shaped mail sorting room behind it; the lunch room, store, strong room and office along the south; and the enclosure of the former verandah along the west to provide (south to north) a cleaner's room, lockers, toilets, loading dock, night mail and contractor's rooms. The original planning of Ayr Post Office comprised a symmetrically
