164a and 164b, Castle Street

Numbers 164A and 164B, Castle Street form an unusual pair of houses. The southern house (164A) dates to the 18th century, while the northern house (164B) is a later 19th-century addition, built in a matching style.

Number 164A has a facade of red and grey brick with rubbed red brick dressings and white stone quoins, a brick cornice, and a coped parapet. There is an old tiled roof, two hipped dormers, and an end chimney. It has three windows with unbarred sashes, and a central door featuring a good rectangular fanlight.

Number 164B is constructed of red brick with an eaves cornice, white stone dressings, and a coped parapet. It also has an old tiled roof and is two storeys high. The northern window is identical to the two-storey bay of 164A. The southern window has a stone lintel. The door is framed by a stone architrave and a dentil cornice, with heavy 19th-century detailing.

Numbers 162 to 174 (even), along with the street boundary wall at number 174, numbers 182 to 190 (even), and number 196, form a group with numbers 169 to 175 (odd), the railings and gate at number 169, and the street boundary wall at number 171.
