Description

No. 21 High Street is a house that was once two separate dwellings, dating from the early to mid-16th century. It was floored and had a stack inserted in the 17th century, with alterations made in the 19th century and an extension added in the 20th century. The building features a timber frame that is rendered and weatherboarded, topped with a thatched roof. It likely started as a small two-bay open hall. The house has one storey and an attic, with a low plinth. The central entrance has a plank door set in a moulded surround. On either side, there are 19th-century five-light shop windows that project out as oriels on brackets. To the right of the centre, there is an attic three-light window with eyebrow thatching. The right end has an internal stack with a rebuilt cap, and the exposed plates are visible. The left end is weatherboarded and features two-light casements, while the right end has a rendered panel with pargetting. There are 19th and 20th-century outshuts at the rear. Inside, the building showcases exposed framing with tension braces, cambered collars supporting a soot-blackened clasped purlin roof with curved windbraces, and stop-chamfered axial bearers and joists on the ground floor.
