64 And 65, St Mary Street

64 and 65 St Mary Street is a pair of houses built in 1820, now functioning as offices under single ownership. The building likely has origins in the early 17th century, with alterations made in the mid 18th century and 19th century. It features painted roughcast and render over limestone rubble, with painted freestone dressings and a stone slate roof that includes three small hipped dormers. Brick stacks are located at the left gable end and the rear.

The exterior consists of two storeys with an attic and a three-window range, along with a bracketed gutter. The outer dormers have 3/3-pane sash windows, while the centre features a 2-light casement window. A 20th-century door, located left of centre, is set within an 18th-century raised chamfered doorcase topped with a pediment on consoles. This door is flanked on both floors by 3-light stone-mullioned windows with 19th-century sashes between 2-pane fixed lights. To the right on the first floor is a similar window with small panes above an early 19th-century 8-over-8-pane sash window. The far right has a moulded hood on brackets above a chamfered surround and a 19th-century four-panel door. The rear of the building has been rebuilt in the 20th century.

Inside, the ground floor features a chamfered axial beam at the centre, and to the left gable end, there is a restored stone Tudor-arched fireplace. A large chimney-breast at the rear has a 20th-century fireplace. The cellar below is currently used for commercial purposes. The first floor includes two cross-beams with run-out stops and an open fire with a moulded surround and mantelshelf at the left gable end. The roof is a three-bay collar-beam structure with tenoned purlins. Historically, this building was known as The Black Horse Public House in the 18th century.
