Duffryn Farmhouse

Duffryn Farmhouse is a building constructed from rendered and painted sandstone rubble, topped with a concrete interlocking tile roof. The entrance front features two windows to the left of the door, both of which are 3 + 3 pane timber casements. The door is a 17th-century plank design. To the right of the entrance is a projecting half-round bread oven, a hall window with four 3-pane lights, and a projecting kitchen wing that includes another window of the same style. This kitchen wing also has a rear window and an outshut at the gable, along with a red brick stack.

On the first floor, the house has four 2-light half dormers with sloping tops. There are three ridge stacks, with the central one backing onto the cross-passage being ancient and showing weathering that suggests the roof was originally thatched. The downhill gable features an attached garage, while the uphill gable has two 19th-century sash windows. A cell beyond the third chimney may have served as a granary before being incorporated into the house.

The garden elevation on the left side has two 20th-century steel casements, a French casement, and a projecting stair-turret. The rear includes a door to the cross-passage, a modern casement, and French doors with a casement below in the lower kitchen. The upper floor mirrors the earlier dormers and includes a modern casement in the stair gable.

Inside, the cross-passage contains a late 19th-century stair with turned balusters. The original stair from the 17th-century stair-turret has been removed, which was necessary when a corridor was added along the rear upstairs wall in the late 19th century. Many of the old fireplaces have been removed or are concealed. The beams in the cross-passage feature bar-and-runout stops, while those in the parlour have lambs'-tongue stops. The 17th-century roof includes three principal rafter trusses below the main stack and one above, with two tiers of purlins and a ridge piece; most of the rafters appear to be original.
