11 And 11A, Lower Bridge Street

This building comprises an undercroft and town house, now used as shops and offices. The undercroft dates before the 18th century and was extended in the 18th century. The front facade was constructed around 1760, with a 19th-century cellar added later. The building is constructed of sandstone and brown brick in Flemish bond to the front, with some rendered areas, and has a hipped grey slate roof with a ridge running at a right angle to the front.

The exterior features a cellar and four storeys, including street and Row levels. The rendered shop front has a simple single-pane window on each side of a modern glazed door with sidelights. A fascia has two moulded brackets and lead flashing. The Row, accessible from a staircase in the neighbouring building at number 9 Lower Bridge Street, has a timber rail with turned balusters, rendered end piers, two unfluted Doric pillars, and a stallboard 3.3 metres from the front. There is a boarded Row walk and a timber bressumer; two beams, likely made of oak, span the southern end. A replaced door of six fielded panels with a three-pane overlight and a replaced window are also present at the rear of the Row walk. The third storey has three sash windows that are almost flush with the facade, and the fourth storey has three six-pane sashes. Some of the sashes have been replaced with horn-patterned versions, all are fitted with painted stone sills and rusticated wedge lintels with false keystones. A parapet with plain coping sits atop the building, and a lateral chimney is located on the south side. The rear of the building features a replaced door within a round-arched opening and replaced windows with cambered heads, one to the second storey and two each to the third and fourth storeys.

The interior includes a probable early 19th-century rock-cut cellar, 2.4 metres below floor level, with damaged rock-cut steps. Much of the pre-18th-century undercroft is obscured. A C18 rear extension begins 11.75 metres behind the street and is barrel-vaulted in brick. There is no visible access from the Row level to this extension. The Row storey incorporates a side passage, six-panel doors, an open-well open-string staircase with shaped brackets and three column-on-vase balusters per step, and an under-stair cupboard with a four-panel door on HL hinges. The landing on the third storey has a probable early 18th-century archway, and six-panel doors. The front room on the fourth storey exhibits skirting, a dado rail with one row of linenfold panelling below and two rows above, a cornice at door-head level, a king-post truss, and purlins.
