Saint Mary's Auction House

Saint Mary's Auction House is a mid-terrace townhouse and business premises, constructed in painted roughcast with a slate roof and red brick stacks. It stands three storeys high, with a cellar and features a three-window range. The shop front, dating from the late 19th or early 20th century, has a central deeply recessed pair of doors with glazed upper panels and a large rectangular overlight. This is flanked by canted plate glass panes between two large plate glass shop windows that have wide timber sills with thin turned shafts at the corners. Inside, two cast iron columns support a concealed lintel, with C20 cellar vents beneath. The shopfront casing includes fluted pilasters on either side, a fascia, and a modillion cornice.

On the first floor, there are cambered-headed 12-pane hornless timber sashes, also with cambered heads, and painted slate sills. A raised stucco band separates the floors. The upper floor features cambered heads on the panes of the top sash, with flat heads under the eaves. It has hornless small-paned sashes and painted slate sills, along with a painted renewed eaves cornice adorned with small modillions and cast iron rainwater goods above.

Although the 18th-century staircase between the first and second floors was removed around 1993, some panelled doors remain. A late 19th-century dog-leg stair is located at the back wall corner, featuring turned balusters and newels with ball finials. The shop window includes two late 19th-century iron columns made by T. Jones Priory Foundry in Carmarthen.

The rear auction room has a continuous cast-iron rail fronting a three-sided gallery, which has a decorative bowed front and cast-iron brackets with a circle motif on brick piers, dated 1899. The gallery's ironwork follows a neo-rococo pattern, similar to that of the Tabernacle Chapel on Waterloo Terrace. The end of the gallery has a similar balustrade that may have been reset in the 20th century. The roof is supported by four trusses with iron ties, diagonal struts, and a central rod.
