1 St Mary's Street

1 St Mary's Street is a double-fronted corner building constructed in painted stucco, featuring three storeys and a cellar. The left side has a two-window layout with a shopfront on the ground floor. This ground floor includes a recessed half-glazed door with an overlight to the left of a plate-glass shop window, which has a canted side-pane. The shop window, altered in the late 19th century, features a timber sill, a roughcast plinth, panelled pilasters with a fluted centre panel, brackets, a plain fascia between the brackets, and a cornice. The first floor is framed by broad raised strips on either side and above the two cambered-headed sash windows. These sashes have a six-pane upper section and a plate-glass lower section, with painted stone sills. The upper storey has smaller 12-pane hornless sashes with flat heads. A timber eaves board extends across the eaves of the recessed range to the right.

The right range also has a two-window layout, with three later 20th-century small plate-glass shop windows on the ground floor, and a larger window to the left that may have once been a door, along with a pair in the centre right. This range lacks sills. The upper floors each feature two well-spaced 12-pane sashes with stone sills, with the upper storey sashes being shorter. A cast iron street sign reading 'St Mary's Street' is present. The entire façade angles inwards towards the left, though the eaves follow the street line. The angle to Quay Street is chamfered at the ground floor, with the chamfer running out as a curve.

On the Quay Street side, there is a one-window range similar to the other side, with 12-pane horned timber sashes on each storey, again shorter on the upper floor. The ground floor window has a flat head but a cambered top to the panes of the six-pane top sash, and a plate-glass lower sash. There are also a pair of 20th-century boarded cellar doors set in a high plinth beneath. A cast iron street sign reading 'Quay Street' is also present, along with a plain eaves board.

The ground floor has been extensively altered, featuring 20th-century details on the first flight of stairs, with curved quarter round landings leading to the first and second floors. The upper flights retain earlier 19th-century stick balusters and a thin rail. Panelled shutters are present in the Quay Street windows.
