Pantyffynnon Isaf

Pantyffynnon Isaf is a house and outbuilding built from whitewashed rubble stone. The farmhouse features a slate roof with one rebuilt red brick chimney on the left, while the other chimney has been removed. The double-fronted, low two-storey facade is offset to the right and includes two 4-pane horned sash windows on each floor, with a door situated between them. The upper windows are shorter and positioned under the eaves, while the lower openings have cemented heads, possibly with timber lintels. The door features a shallow-curved projecting drip above it and is a 20th-century addition. Slate sills are present throughout. At the rear, there is an added rubble stone lean-to.

The outbuilding, likely a cowhouse, is a single-storey structure with a roof that is partly covered in corrugated iron and asbestos, and partly in slate. It has a door with a timber lintel and a small window located to the left of the centre. An addition on the right end is made of rubble stone and includes a door that adjoins the original range, which has red brick angle quoins. The rear of the outbuilding features a 20th-century brick milking parlour and a door with a timber lintel to the left. The interior of the buildings is not available for inspection.
