Cors-y-Garnedd

Cors-y-Garnedd is a two-storey building constructed of rubble, with the house section whitened and covered by a recently renewed continuous slate roof. The building features a rubble gable parapet on the left and end chimneys on both the house section and the byre gable end on the right, with moulded capping and weather-coursing. The house gable is partly built on rock. The entrance is off-centre and has a recessed modern door. To the left of the entrance is an 8-pane casement window, followed by a 6-pane sash window from the third quarter of the 19th century. To the right of the entrance, there is a recessed 4-pane casement window. The first floor has three small 6-pane sash windows located under the eaves. The rear of the building has modern fenestration and a later outshut with modern windows and an entrance on the gable side, along with five skylights on the rear roof pitch.

The byre section includes a 19th-century gabled upper entrance on the left, featuring a boarded door and external rubble-parapeted steps. There is a primary entrance with a boarded door, flanked by small plain-glazed windows, and similar windows are found at the rear. The right side has a rubble gable parapet, and as of February 1995, the rear roof pitch is being re-laid.

Inside, there is a cross-passage with a beamed ceiling, showcasing fine ogee-stopped chamfered beams and good opposing post-and-panel partition screens with grooved decoration. The left screen has later pine restoration at the rear and features a plain pine doorcase from the 18th century. The former hall on the left has a beamed ceiling with ogee stops on the chamfered beams and joists, with the gable end wall beam supported by three rough stone corbels. There is a large end fireplace with bresummer detail, and to the right, a contemporary stone corkscrew mural stair. An entrance into a later lean-to at the rear was created from the original hall window, retaining the stopped-chamfered lintel. The former parlour has a contemporary fireplace, although all ceiling beams have been removed except for the main longitudinal member. A plain 19th-century corkscrew stair leads to the upper floor, which has a boarded partition screen. The upper floor features a 3-bay cruck roof with pegged collars.

The byre section has a 4-bay layout with pegged collar trusses, and a ground-floor rubble dividing wall runs laterally across the third bay.
