20, Shambles

No. 20 Shambles is a house that has been converted into a shop. It dates from the early 18th century, with alterations made in the early 19th and 20th centuries, including a modified shopfront from the 19th century. The building is constructed of orange-brown brick, with the front in Flemish bond and decorative elements made of orange rubbed and gauged brick, while the rear is in English garden-wall bond. The roof is made of pantiles and hipped at the front, featuring brick stacks.

The exterior has three storeys and a two-window front. The shopfront includes a small-pane window to the left of a glazed and panelled door, which has a margin glazed overlight, all framed by plain pilasters beneath a cornice. The first and second floor windows are 12-pane sashes, with the first-floor windows being taller, and both have painted stone sills and flat arches. There are three raised brick bands on the first and second floors. The rear of the building has three storeys and an attic, with a two-window gable wall; the ground floor is concealed behind a yard wall. The first and second floors have 12-pane sash windows, with a blocked opening to the right on the first floor. The attic features a squat 6-pane window and a raised band at the second floor.

Inside, the staircase has been rearranged from the ground floor to the attic and extended to the basement. It retains original column-on-vase balusters, with some original and some renewed, plain newels, some with attached half balusters, and a moulded close string and handrail. On the first floor, the front room has a plain fireplace with a moulded cast-iron grate, while the back room features a hob-grate in a painted stone surround and a two-panel cupboard door with H-hinges to the right. On the second floor, there are two two-panel doors with H-hinges on the landing, and the back room has a hob-grate with sidepieces decorated with birds, lions, and rinceaux. The attic has a lime ash floor and an underceiled roof. Other features noted by the Royal Commission on the Historical Monuments of England have been removed.
