Description
66 St Mary Street is a house in a row with a shop, dating from the late 18th century, with modifications made in the mid-19th century. The building is rendered and features a hipped tile roof behind a parapet. It has three storeys and an attic, with one window. Above the main entrance, there is a hipped dormer with a two-light casement, which sits above a two-storey canted oriel window that has sashes arranged in an 8:12:8 pattern, topped with an upper cornice that extends across the entire front. The 20th-century shop front includes a six-panel door on the right leading to a throughway, and the mid-19th century flat hood remains across the full width of the building. There is a mid plat band and a shallow blocking course at the coped parapet, with no chimney stacks visible from the street. The rear of the building is gabled and features a lower rendered range that includes a tall two-light half-dormer with a transom and some Art Nouveau glass. The interior has not been inspected.
