21 High Street

21 High Street is a tenement building from the earlier to mid-19th century, featuring three storeys and three bays, and is part of a terrace. The ground floor includes two shops and a pend entrance. The shopfronts are made of painted ashlar, while the upper sections consist of painted, tooled, squared, coursed sandstone with painted polished ashlar margins. The rear of the building is constructed from rubble with red sandstone ashlar dressings. Notable architectural details include an eaves course, raised cills, and a central polygonal yellow brick stair tower at the rear.

The shop windows are fitted with fixed plate glass, while the upper floors have timber sash-and-case windows with four-pane glazing. The rear features a mixture of glazing patterns in timber sash-and-case windows. The roof is covered with grey slate, and there are ashlar-coped brick stacks at the rear, topped with circular clay cans.
