Maerdy Farmhouse

Maerdy Farmhouse is a two-storey building constructed from rubble stone that was once whitewashed, now covered with 20th-century concrete tiles. It features a large stone stack at the eastern end with battered sides, a rendered ridge stack, and a western end stack serving the service range, all under a single ridge line. The main house has a three-window façade with 20th-century windows, including a pair of casements, a single casement, and a triple casement above, as well as a door and a four-light casement below. The door is half-glazed and located in a stone porch with a slate roof. There is a southeast rear wing with a 20th-century southern addition, and the service range to the left of the main front is rendered with 20th-century details and has two windows over two storeys.

Inside, the southeast front room features a massive fireplace beam over a deep fireplace that includes a bread oven beneath a blank ogee arch. The room has heavy cross beams, one at the center, one over the fireplace, and another over a timber-framed hall partition. Scribed joists run axially, except along the rear wall, indicating a former passage or stair. The rear wall is paneled, and there is a six-panel door with scribed moldings leading to the stair hall. The staircase has a single flight with small square newels and renewed balusters, along with scribed joists. The southwest room contains one large beam and another over the fireplace, with scribed joists. The northeast rear room has four cross beams. On the first floor, there are fine collar trusses with purlins that are alternately threaded and trenched, with the collars dovetail morticed and pegged, resting on projecting oak pads. Timber-frame partitions are located on each side of the stair hall, while the rear wing has two trusses with altered collars.
