Dyffryn Farmhouse

Dyffryn Farmhouse is a two-storey building with an attic, constructed of whitewashed rubble and topped with a slate roof that features rubble end stacks. At the rear, there is a continuous outshut, and to the west, a long adjoining range. The southern front has a layout of two windows on the upper floor and one on the lower floor, all featuring small-pane horizontal sash windows. To the right of the center, there is a planked half-lit door with small panes, flanked by a 16-pane sash window on the left and a late 20th-century casement window on the right that matches the sashes above. The building has mainly stone sills and timber lintels. A blocked doorway on the far left would have provided a lobby entry in the 17th century. The outshut includes three small windows of various styles with timber lintels and a door similar to the front. The eastern gable end has three 2-light casement windows on the ground floor and one on the first floor, while the western gable end features a glazed door at the rear of the adjoining range.

The adjoining single-storey range, which was formerly stables, is also made of whitewashed rubble and has an asbestos slate roof with skylights at the front. Its front elevation includes three pairs of French doors and a small window, while the rear has a half-lit door and three windows with timber fascia below, likely originally stable doors.

Access to the interior was not available at the time of inspection, but it was reported in 1991 to contain a massive cross beam with a deep chamfer, a substantial arched bressumer above the left fireplace with a domed bread oven, and a late 16th-century chamfered-arched dressed-stone doorway with diagonal stops to the right, which previously opened onto winding stone stairs that were later relocated to the rear outshut.
