Head Post Office

The Head Post Office is a large corner building constructed of Portland stone in a free classical style. It features channelled rustication on the ground floor and iron railings around the basement areas. The building has four main storeys, plus two additional storeys in a steep, slated roof adorned with elaborate gables and an octagonal lantern.

The front facing Westgate Street consists of five blocks, with the central and end blocks being more prominent. Each of these blocks has three-window sections with attics featuring Dutch gables, and dormers are positioned in the roof slope between the gables. The central bay showcases tripartite windows on the top floor, above windows that are topped with scroll pediments, dark stone columns, and a balustrade. There is a small Corinthian entrance portico flanked by large round-arched windows.

The central bay is flanked by four-window bays that have paired windows on the top floor, segmental pediments above the architraves, and balconies on the second floor. The mezzanine floor has squarer windows situated above sash windows. The end bays mirror the central bay's design but feature triangular pediments above the second-floor windows in the outer bays, along with doorways that have pedimented doorcases.

The corner bay includes a polygonal turret topped with a steep slate roof and a miniature lantern. The first block along Park Street matches the design of the blocks at the Westgate Street end. The building continues as a recessed block of seven windows in a simpler style, alternating between segmental and triangular pediments for the second-floor windows. Following this, there is another block that aligns with the corner block, and the elevation continues to the corner in an even simpler design.
