15, Derby Street

No. 15 Derby Street is a house that has been converted into a shop. It was largely built in the early 18th century, with the possibility of an earlier core. The building was refronted in the early 19th century and underwent further remodelling in the late 19th or early 20th century. The exterior is constructed of brick in Flemish bond, featuring blue headers on the side elevation, and is partially rendered at the ground floor.

The front windows have stone dressings, and the roof is covered with slate. The return elevation towards the passage includes a doorway near the center, with a stair window directly above it. To the left, there is a 4-pane sash window in an earlier opening, and a 2-light wood mullioned and transomed window with iron glazing bars and a flat-arched brick head above. The early 19th-century reeded doorcase adds to the character of the entrance. The stair window also features iron glazing and extends through two storeys above.

The gable facing the street has been extensively remodelled, although the gable itself, which is coped and has kneelers, may date back to the original early 18th-century construction. The late 20th-century shop front is present at street level. Above, there are two early 20th-century mullioned and transomed windows, along with 4-pane sash windows in the attic, all featuring stone voussoir heads. The building has an axial stack. The interior has not been inspected.
