Description
Garth y Fog is a small, two-storey vernacular farmhouse built in 1796. It features rubble construction with a renewed slate roof and kneelered rubble gable parapets. The farmhouse has end chimneys with weather coursing and moulded capping. The entrance is slightly off-centre to the right and has a boarded door. To the left of the entrance is a small, recessed 9-pane fixed window, followed by a 4-pane near-flush 19th-century casement, with another similar casement to the right of the entrance. Under the eaves, there are three smaller casements, and above the door is an inscribed stone that reads "1796" and "L E A."
To the left of the main structure is an adjoining single-storey wash house with a mono-pitched roof, which has a boarded door and a plain-glazed window on its southwest face. This addition features a small squat stack at the southeast corner topped with a 19th-century octagonal moulded chimney-pot and has an old slate roof. At the rear of the farmhouse, there is another casement and a small light, with an entrance under the eaves that has a recessed boarded door with a small glazed panel. The rear roof pitch includes two skylights.
The interior was not accessible during the inspection in November 1994.
