10 and 12, St Owen Street

10 and 12 St Owen Street are former houses, now used as offices, dating from the late 18th century. The buildings are constructed of brick with a slate roof and feature a central brick stack. They have a symmetrical three-storey design with a seven-window range, where sash windows are present on the first and second floors, although the central window appears to be blocked. A stone band and a moulded pediment with a possibly false lunette window enhance the façade.

The buildings have two-storey recessed wings that contain single sash windows and six-panel doors with plain overlights, along with banding and a parapet. The central entrance features a six-panel door with a fanlight and an open pediment hood supported by round pilasters.

Inside No. 12, there is an early 19th-century dogleg staircase with stick balusters and a swan neck rail. The second floor includes an 18th-century fireplace, wall cupboards, and four four-panel doors with architraves. On the first floor, there are two 18th-century fireplaces, a 19th-century wall cupboard, a picture rail, architraves, and five six-panel doors with architraves, along with a reeded architrave to a panelled opening, an arched ceiling, and a 19th-century fireplace. The ground floor features four six-panel doors with architraves, coving, architrave and panelled shutters on the windows, an architrave on a cupboard door, a probable 18th-century fireplace, one four-panel door, a decorated ceiling, coving and rails, two 19th-century fireplaces (one with tiles), a dado rail, and lined reveals with architraves to an arch in the hall. The cellar is mainly brick-lined and has chamfered ceiling beams, a plank door, and stone stack bases.
