Description
Gilfach farmhouse, which includes an attached former cow house, is a 1½-storey building constructed of rubble stone, featuring a stone tile roof and a tall central stone chimney. The main entrance is centrally located and consists of a boarded door set in brick jambs. To the left of the chimney, there is a 2-light window and a 2-light roof dormer. To the right of center, an inserted window occupies a former cross-passage doorway. The left gable end has a lower storey with a replacement 2-light metal-framed window, an inserted window to its left, and a narrow window to its right. The gable is box-framed and features a 2-light metal-framed casement window.
The rear wing is slightly set back from the main range's gable end, with a replacement 3-light window and a small window on the left side. Above this, there is a close-studded gabled bay with a jettied gable supported by consoles, adorned with lozenge panels, and a replacement 3-light metal-framed window. The opposite rear wall of the wing has a 2-light window with a sill. The rear of the house features a 3-light window in the former cross-passage doorway.
On the downhill side of the farmhouse is the cow house, which has three split boarded doors. A 2-light loft window is present, along with a gable that includes pigeon holes. An added lean-to structure against the downhill gable end has a split boarded door. The rear of the cow house features an added outshut with a slate roof, a boarded door with brick jambs in the downhill end wall, and a 2-light window on the right side of the rear.
Inside the farmhouse, to the left of the entrance, is a sub-medieval hall that has a flagstone floor, a fireplace with a large chamfered timber lintel, and a bread oven. The spine and cross beams are decorated with ogee stops. A post-and-panel screen has mostly survived, positioned where a surviving cruck truss is located. The rear wing also contains a fireplace with a large timber lintel. The cow house has a restored 3-bay roof.
