4, Duke Street

No. 4, Duke Street is a town house dating probably to the 17th century, with alterations in the 18th century and the 20th century. It is constructed of brown brick in a Flemish bond to the front, with a grey slate roof running parallel to the front. The house has a cellar and three storeys, with a double-fronted design featuring two windows per storey. A stone staircase of two repaired flush steps and an additional repaired step leads to a four-panel door with an overlight, sheltered by a repaired flat hood supported by two shaped brackets. The windows are flush sashes with lead apron sills and gauged brick cambered heads; the first and second storeys have 16 panes, and the third storey has a combination of 8-pane and 4-pane leafs. A three-course floor band is present on each upper storey. The roof has an oversailing parapet above a moulded stone cornice, and old brick chimneys are visible on the west gable and rebuilt above the ridge on the east gable. The presence of unbroken vertical joints at the centre and near the ends of the second and third storeys suggests the fenestration was replaced with the current mid-18th century sashes. Rear windows have been renewed.

The rock-cut and brick cellar has close studding in the east wall. A front room on the first storey retains early 18th century panelling, with one row below a dado rail and a taller row above. A remnant of a round archway is visible to the rear, and the rear west room contains a corner fireplace, along with a former inglenook featuring an oak bressumer. Upstairs, corner fireplaces are fitted with 19th-century cast-iron grates. The staircase and doors have been renewed.
