10-12 Bank Quay

10-12 Bank Quay is a former bank built in the late Georgian style, featuring a square plan with three storeys and four bays. The exterior walls are covered in scribed roughcast, which is painted on the main elevations, and the building has a hipped slate roof with wide bracketed eaves and a roughcast stack located behind the ridge. Although some slates have been replaced, the roof still includes some original large thick slates.

On the ground floor, there is a doorway in the right-hand bay that retains its Tuscan pilasters, although the original pediment has been removed. This doorway features double fielded-panel doors and a replaced plain semi-circular overlight. The other ground-floor bays have round-headed moulded architraves with partially fluted pilasters and panelled tympana, leading to replaced windows with a sill band. To the left, there is a two-bay projection that has a similar window with Tuscan pilasters, but it lacks its original head. Further left, there are double boarded doors beneath a segmental overlight.

The middle and upper storeys of the main range display moulded keyed architraves with sill bands, featuring 12-pane hornless sash windows on the middle storey and 9-pane hornless sash windows on the upper storey. The left-side projection contains a 4-pane sash window at the upper left with a similar architrave. On the right side, there is a 1½-storey gabled wing with sliding wide boarded doors beneath an inserted attic window.

The left side wall of the main range includes 12-pane and 9-pane sash windows to the left of the two-storey projection. The rear of the building has three windows that are similar to those at the front.

Inside, the main entrance leads into a vestibule featuring late 19th-century details, including glazed and relief moulded tiles on the dado and a half-lit panel door with flanking panels that incorporate etched glass. The vestibule opens into a stair hall that has a bracketed ceiling cornice and a full-height open-well stair with plain balusters and moulded tread ends. Most rooms contain panelled doors and panelled shutters, and some still have fireplaces with panelled chimneypieces.
