Exterior
Belongs to a group of 6-12 Castle Street.
A near symmetrical "artisan-classical" terrace of 10 bays, originally comprising 4 houses of 3 storeys with attics. Pediment over 4 central bays, and strong rhythm imposed on the design by continuous cornice over ground floor, carried on fluted Ionic columns articulating the original property divisions, and framing doorways, and at first floor by alternating paired round-arched windows linked by balconies. The front is stucco, drafted in the lower storey and scribed above, with rusticated angle pilasters, and slate roof on bracketed eaves, with brick stacks. Ground floor has central tripartite sash window but otherwise disposition of detail is asymmetrical, reflecting unequal division into separate properties. Nos 6 and 8 at the R (N) end are 2-bay houses with doorways in the R-hand bay, although in the upper storeys No 6 has only a single window. No 10 was also originally a 2-bay house, probably with lower-storey shop, under the central pediment, while No 12 was a 4-bay house, although Nos 10 and 12 are now amalgamated into a single property. The front is stucco, drafted in the lower storey and scribed above, with rusticated angle pilasters, and slate roof on bracketed eaves, with brick stacks. The doorways have doors incorporating round-headed panels and plain overlights, except No 12 which has a small-pane overlight. The windows in the lower storey 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 had 2-light casement windows with transoms, set in round arches in paired outer and central bays; these have cast-iron balconies of lattice-work over Greek key frieze. Upper storey has 9-pane sash windows, horned to Nos 10 and 12, hornless to Nos 6 and 8, and sill band. A shallow open pediment spanning the central 4 bays has a round-headed sash window in a rusticated architrave.
Rubble-stone rear with horned sash, and projecting out on the R side with rendered wall and wide bracketed eaves.
