12, Parliament Street

No. 12 Parliament Street is a house, now used as offices, built around 1797 with 20th-century alterations. The building is constructed of brick, featuring a painted basement and painted ashlar dressings, topped with a slate mansard roof and a rendered gable stack. It has a plinth, ground floor, and first-floor sill bands, along with a slab-coped parapet. The windows are set beneath brick flat arches. The structure has three storeys plus a basement and attics, with a three-window range of 15-pane sashes above, and three 9-pane sashes. Above these, there is a segment-headed dormer with a single-pane window.

On the ground floor, to the right, there is a wooden doorcase with Ionic three-quarter columns, a dentillated cornice, and a pediment. The round arched doorway has steps leading to a fielded six-panel door with a blank fanlight. To the left of the doorway, there are two 12-pane sashes, and below them, two boarded-up basement openings with brick flat arches.
