Mona and Mona Isaf

Mona and Mona Isaf comprise a two-storey, five-window range building originally constructed as an inn, along with a shorter, two-storey, three-window wing to the northwest (Mona Isaf). A U-shaped range of lofted stables and cartsheds surrounds a large rectangular courtyard to the rear, connecting with the northwest wing. The main house is built of local rubble masonry with rendered elevations, though the rear elevation is significantly weathered. It features a first-floor sill band on the front and left return elevations, a roof of large, thin slates, and brick gable stacks. A single brick stack is positioned to the rear, to the left (northwest) of the third window. A single-storey lean-to is situated to the left (southeast), concealed from the road by a rubble wall, and a modern, half-glazed gabled porch is at the rear. The front elevation, facing northeast, has a central panelled door beneath a rectangular fanlight with radiating glazing bars. Windows are hornless sashes; the ground floor windows are 15-pane, while the first floor windows are 12-pane, with slate sills on the ground floor. The left (southeast) gable return has one 12-pane window on the first floor, and the lean-to has a 12-pane sash and a boarded door to the right (northeast). The rear of the house has weathered windows, which are likely late 19th-century replacements, being four-pane, horned sashes. A square-headed opening provides access to the brick-vaulted cellars. The northwest wing is constructed of local rubble masonry with a slate roof, a brick gable stack at the right (northwest) end, and a ridge stack offset to the left (southeast) end. This wing originally had a three-window range with a central doorway, but has been extensively renovated, and few original hornless sash windows remain, and the building is now semi-derelict.

Inside the main house, the principal rooms are located at the front. The ground floor rooms on either side of a central hallway feature an axial corridor to the rear, retaining an original stone flagged floor. A dog-leg staircase with a clasping handrail and stick balusters leads to a first-floor axial landing. A second staircase, located at the northwest end of the house, was removed in the mid-20th century. Most principal rooms retain panelled shutters and dado rails, and many bedrooms have small cast-iron fireplaces.
