Description
16-18 Clwyd Street is a three-storey building with four windows, featuring pairs of windows grouped on each side. The exterior is roughcast and topped with a slate roof, with a brick chimney stack to the right of each former house. The first and second floors have horned four-pane sash windows with margin lights; the first-floor windows are set under segmental heads, while the second-floor windows are positioned just below the eaves. Centrally located at the first floor is a figure of a crowned bust, with an iron sign bracket above it.
On the ground floor, there are segmental-arched doorways on the outer sides, each containing panelled doors. The inner sides have shop fronts that are connected by a continuous moulded cornice. The rear of the building, partially visible, is roughcast on the left and brick on the right, with a shallow gabled rear wing in the center. The upper storey features two six-pane sashes in the gable and wooden casements in the main range; the ground floor at the rear is not visible.
Number 16 has windows with raised surrounds and keystones. Its shop front includes openings framed by pilasters with raised round-arched panels, supporting a fascia adorned with a dog-tooth band. To the left is a half-glazed panelled door with a plain fanlight, and to the right is a three-light window with arched heads.
Number 18 features a four-panel door with a plain-glazed overlight on the far left. Its shop front, possibly from the late 20th century, has details similar to those of Number 16, with pilasters and raised panels supporting a fascia. It includes a central glazed door with large panes beneath a two-pane overlight, flanked by two-light shop windows, also with arched heads.
The interior has not been seen.
