Description

Mark House is a country house built around 1800. It features Flemish bond brickwork, a moulded stone cornice, a brick parapet with plain coping, and a double span slate roof with coped verges and end brick stacks topped with stone caps. The house has a symmetrical frontage with three storeys and three bays, where the central bay slightly projects forward. The second floor has 20th century two-light casement windows, while the first floor has 12-pane sash windows. The ground floor showcases tripartite 20-pane sash windows with cambered heads, all adorned with rubbed brick voussoirs.

The central door opening has sidelights and an elliptical head, also featuring rubbed brick voussoirs, a six-panelled door, and an overlight with radiating glazing bars. To the right, there is a two-storey flanking brick pavilion with a slate roof that has a ridge at right angles to the main frontage. This pavilion has a pedimented gable with a moulded stone surround and a tall semi-circular head sash window with glazing bars set in a shallow recess at the center of the frontage. The pavilion is connected to the main house by a short section of brick wall that includes a shallow semi-circular headed niche. Inside, there are some contemporary features, including a staircase and window shutters on the ground floor.
