Description
1 High Street is a Grade II listed building featuring a rendered, part scribed, six-window front with broad end pilaster strips and a band course for Nos 1 and 1a. It has a tall hipped slate roof with a central brick chimney stack at the ridge and coved cornice eaves. The building includes four pitched roof slate-hung dormers with modern windows. The first floor showcases Georgian 12-pane sash windows. The ground floor has been altered with modern shop fronts and doors, including a left end with a console bracketed hood and panelled soffit. The steep gabled brick rear elevation has extensions and a lean-to outshot, retaining small-pane sash windows for Nos 1 and 1a, while No 1b features modern windows.
Inside No 1, the interior retains largely original roof trusses, an 18th-century staircase with turned balusters and a swept-up handrail with a wave profile, panelled doors, and a fireplace in the basement at the rear with a stopped chamfered lintel.
