Mayen House

Mayen House is a large two-storey house, likely built around 1788, with significant additions and internal remodelling completed by architect A Marshall Mackenzie between 1892 and 1893. The house faces east and is set over a raised basement, featuring a three-bay front and a five-bay return on the south elevation. The exterior is harled with tooled granite margins and dressings. The central door is concealed by a gabled porch added in 1893, which is accessed by a flight of steps that oversails the raised basement and is adorned with an ornamental cast-iron balustrade. The outer bay windows are set in long, shallow round-headed recesses that extend from the basement to frame tripartite windows on the ground floor and Venetian windows on the first floor, with a simple round-headed window in the centre of the first floor. The south-facing return elevation is plain, featuring an additional canted end bay at the southwest that rises to full height, along with an off-centre projecting canted window at the basement and ground floor. The irregular rear elevation has been remodelled following some demolition and includes a central stair window with two-pane glazing. The front features a band course and angle quoins, with rainwater goods dated 1893. There are substantial granite stacks in the centre of the piended platform roof, along with an additional ridge stack at the gabled rear.

Inside, the entrance hall has a reeded Corinthian screen and original raised and fielded panelled doors with corniced overdoors. The wooden staircase from 1893 features barley-sugar twist balusters and swag carved decoration on the outer tread ends. The first-floor landing has been remodelled with arcades and pilasters. The dining room includes a black carved and columned chimneypiece from 1893, while the drawing room features a carved and swagged Adamesque chimneypiece from the same year. There are also some decorative plaster ceilings and cornices.

Additionally, there is a detached northwest wing, built in 1788, which is a two-storey, three-bay building facing south and set back at the northwest, likely serving as a former kitchen. This wing is harled with harl pointed rubble and tooled granite dressings, featuring an irregular three-elevation front, a large later rear garage entrance, some blind windows, and four- and twelve-pane glazing. It has an off-centre ridge stack and a piended slate roof.
