Tan-y-Celyn

Tan-y-Celyn is a rubble cottage that stands one-and-a-half storeys high, featuring a renewed slate roof and a pebble-dashed front. On the right side, facing the road, there is a projecting gabled end chimney with a rendered stack and a plain cornice band, while a modern chimney is located on the left at the northeast corner. The front has an irregular two-window arrangement with a central entrance beneath an early 20th-century conical porch hood made of metal, supported by scrolled iron brackets. The entrance features an original stopped-chamfered oak door frame with a boarded plank door. Flanking the entrance are 20th-century two-pane casement windows, and above are two gabled brick dormers with similar windows; the dormer on the right has leaded glazing. The roof level appears to have been raised, likely in the 19th century, as indicated by evidence on the west gable.

To the east gable, there is a 19th-century recessed 12-pane sash window with a modern window above it. At the rear, there is a second-quarter 18th-century extension that has been altered in the 19th century, forming an L shape with the main cottage. This extension also features a 12-pane sash window on its eastern return, set within a gabled dormer that has modern bargeboards.

A single-storey modern porch extension connects the cottage to a former barn to the east, which is now part of the house. This barn is also single-storey, constructed of whitened rubble with a modern slated roof. It has a window on its long south side and two modern timber-clad gabled dormers on each long side, with modern glazing throughout. The east gable has a modern glazed door with a window above it. The barn was previously a loading bay and retains an exposed timber lintel with a wooden hoist beam.

Inside, the ground floor features a beamed ceiling with rough-chamfered beams and plain hewn joists. There is a large fireplace on the right, which was part of the former hall, with an oak bressummer. Mortising on the underside of the main beam to the left of the door indicates the position of a former post-and-panel partition that was recorded in 1966 and has since been removed. A raised and fielded second-quarter 18th-century panelled door leads to the first floor, accessing the rear section. The primary block has a three-bay roof with collar trusses, including a pair of upper crucks at the center, while the former barn section has a modern roof.
