Description
Ty Capel Isaf is a small, two-storey manse built sometime after the 17th century. It is constructed of whitened, partly rendered rubble with a renewed slate roof and a plain rendered chimney on the northeast side. The exterior features weathercoursing and a plain cornice. The main entrance is on the recessed southeast side, accessed via a modern timber porch. A modern steel-framed window is present on the left side of the porch at ground level, with a matching window above. A single-storey, slated lean-to has been added to the rear, containing a recessed modern window on the first floor. A further modern window is visible on the southwest-facing gable, at ground floor level. The interior was not accessible for inspection in 1996.
