13 Monnow Street

13 Monnow Street is a three-storey building, likely dating from the 19th century, with a double depth plan and a rear wing. The exterior is rendered and painted, probably over brick, and the roof is not visible from the street. The ground floor features a notable late 19th-century shopfront, which includes a double window flanked by a shop entrance on the right and an archway on the left that leads to the office premises above. The shopfront is enhanced by plain pilasters and a fascia, which is interrupted by the apron of the central first-floor oriel. This oriel has a 4 over 4 pane sash window, flanked by curved 2 over 2 pane windows, topped with a dentil cornice. The upper floors are framed by Tuscan pilasters, a moulded floor band, and a cornice above. The oriel is flanked by arched 4 over 4 pane sash windows with keyed and imposted surrounds, while the upper floor features three similar but smaller windows, with the center window set slightly forward, a detail also highlighted by the heavily moulded cornice. The rear elevation has been altered.

Inside, the building has undergone extensive changes due to its conversion to offices in the 20th century, but it still retains some early 19th-century joinery and plasterwork, particularly in the main first-floor front room. A curved staircase with turned balusters and a mahogany handrail adds to the interior's character.
