8 Castle Street

6-12 Castle Street is a near symmetrical "artisan-classical" terrace of 10 bays, originally comprising 4 houses of 3 storeys with attics. A pediment crowns the 4 central bays, and the design is given strong rhythm by a continuous cornice over the ground floor, carried on fluted Ionic columns that articulate the original property divisions, frame doorways, and at first floor separate alternating paired round-arched windows linked by balconies.

The front elevation is rendered in stucco, drafted in the lower storey and scribed above, with rusticated angle pilasters. The roof is slate, set on bracketed eaves with brick chimney stacks. The ground floor has a central tripartite sash window, but the disposition of other details is asymmetrical, reflecting the unequal division into separate properties.

Nos 6 and 8 at the north end are 2-bay houses with doorways in the right-hand bay, although in the upper storeys No 6 has only a single window. No 10 was originally a 2-bay house, probably with a lower-storey shop beneath the central pediment, while No 12 was a 4-bay house. Nos 10 and 12 are now amalgamated into a single property.

Doorways incorporate doors with round-headed panels and plain overlights, except No 12 which has a small-pane overlight. Lower-storey windows are 12-pane horned sashes. Windows to Nos 10 and 12 are framed by moulded consoles with Celtic interlace ornament below the ground-floor cornice. First-floor windows are 2-light casement windows with transoms, set in round arches in paired outer and central bays; these are accompanied by cast-iron balconies of lattice-work over a Greek key frieze. The upper storey has 9-pane sash windows, horned to Nos 10 and 12 and hornless to Nos 6 and 8, with a sill band. A shallow open pediment spanning the central 4 bays contains a round-headed sash window in a rusticated architrave.

The rear elevation is of rubble stone with small-pane sash windows to the middle and upper storeys. An open-well stair survives from first-floor level, featuring plain balusters, hand rail, and moulded tread ends.
