21, Market Place

This is a late 15th-century house with a shop, constructed around 1453 as part of the "New Works" initiated by Bishop Bekynton. It was modified in the 19th century. The building is constructed of ashlar stonework, which is colourwashed, with a Welsh slate roof concealed behind a parapet. A brick chimney stack is also present.

The exterior is three storeys high with an attic, featuring a single wide bay. The ground floor has a particularly fine, projecting mid-19th century shop front shared with the adjoining property at No. 23. This front includes ornamental cast-iron vents in the stallrisers, panelled pilasters with console brackets on the left, a two-light display window with decorative column mullions and rounded top corners, and a glazed doorway to the right within an angled recess. Above the doorway is a semicircular fanlight with a large 19th-century lantern. The upper floors have a wide, shallow canted bay window extending to the full height of the parapet, with sash windows containing 24 panes, 36 panes, and 24 panes on the first floor, and 16 panes, 24 panes, and 16 panes on the second floor. A medieval stone string course runs across the front, interrupted by the bay window. A small, flat-roofed dormer is behind the parapet, along with a flagmast to the left. The stack is positioned to the right and features a raised coped verge.

The rear elevation contains a small pointed-arched window, and two stone mullioned windows with an ovolo moulding. The ground floor window is a six-light design, while the first-floor window is a three-light design. The rear wall also shows the former location of a chimney breast, now capped.

The interior ground floor has a six-compartment ceiling with moulded beams, an 18th-century part dado rail, and other 18th-century features, some of which may have been imported. An elliptical arched recess is found in the east part of the wall. A 20th-century staircase provides access to both upper floors. The front room on the first floor has a two-compartment ceiling with moulded beams. The second floor has a timber and plaster partition forming the western party wall. The roof is medieval, divided into two bays, with arch-braced collar trusses. The centre truss's collar has been removed and a new tie beam installed lower. Chamfered windbraces and two purlins are also present. A single-light, 17th-century casement window with ovolo moulding and three vertical stanchions is in the rear wall, along with a connecting door to No. 23. A vaulted cellar is reportedly located beneath the front part of the shop.

This building forms part of an exceptional late medieval planned urban grouping.
