11a High Street

11a High Street is an attached shop with living accommodation, paired with No 11. It features colourwashed stucco cladding and an imitation slate roof, with rendered stacks—one on the ridge near the left end and the other at the right end. The building is two stories high and has a two-window range, with the upper floor displaying 2-4 pane sash windows.

On the ground floor, the left side has a 6-pane 19th-century transomed three-light shop window, which has shaped heads over the lights and thin pilasters with shaped brackets supporting a stucco moulded cornice above the fascia, which is cut off at the left end. To the right of the centre, there is a doorway closely paired with a right 4-pane sash window; neither of these is aligned with the window above. The doorway is a 20th-century half-glazed door.

The right end gable is roughcast and features a loft light above a two-storey lean-to with a half-hipped gable and a narrow one-window front that includes a glazed door beneath a 4-pane window. All openings on the street front have raised eared surrounds. The windowless end wall facing Parc-y-shwt has a small door at the extreme right, which leads into the angle of the rear wing.
