18 High Street

18 High Street is an early 19th-century building that features shopfronts from 1902 and later. It is a three-storey structure with an attic, forming a symmetrical block as part of a terrace. The ground floor has two shops, while the first and second floors each have three bays, and there are four dormers. The exterior is made of painted whinstone rubble with painted ashlar dressings, and the shopfronts are made of unpainted timber with a black cladding at the base, likely granite. The building has a deep base course and consoled, corniced fascias for the shopfronts, with an eaves course that extends into the cornice. The first and second floors have regular fenestration, featuring tripartite windows in the center and canted windows in the outer bays, with stop-chamfered stone mullions.

The right shopfront, designed in the Art Nouveau style by James Pearson Alison, has a central, recessed, segmental-arched entrance with a broken pediment, featuring two-leaf, three-quarter-glazed timber doors with timber glazing bars and a leaded fanlight. Inside, there is a simple tiled floor in the lobby and decorative leaded lights with a heart motif in the upper outer corners of the windows. The left shopfront has a central, recessed, three-quarter-glazed timber door with a rectangular fanlight and a simple mosaic-tiled floor in the lobby. There is also a recessed timber door tenement on the outer left. The inner dormers have piend roofs, while the outer dormers are canted.

The shopfronts feature fixed plate and leaded glass, and the first and second floors have timber sash and case windows with plate glass, predominantly with 8-pane glazing in the dormers. The roof is covered with grey slate and has a metal ridge. There is an ashlar-coped, red brick stack with circular buff clay cans that is shared with No 14 to the south.

Inside the right shop (No 16), the walls are lined with glazed ceramic tiles, and there are dark timber shelves with turned supports, a Lincrusta frieze, a dark timber chimneypiece, and a plain cornice. The rear room of No 16 features a single cast-iron column supporting the ceiling and cast-iron frontages of bakery ovens.
