Penddaulwyn Fawr, including attached farm building

A 2-storey 2-window house of whitened rubble stone and slate roof with brick stacks (the R-hand rebuilt). Openings have brick segmental heads. The central entrance has a boarded door in a half-glazed lean-to porch. Wooden cross windows under cambered heads incorporate casements. An added lean-to is against the L gable end. The rear has an outshut incorporating a dairy on the R side, with mid C20 windows on the L side.

The earlier lofted farm range is against the R (downhill) gable end, and is limewashed rubble with slate roof. Openings have wooden lintels. At the L end, adjacent to the house, is a cross-passage doorway, to the R of which are stone and brick steps to a loft doorway beneath the eaves. Further R are 3 cow-shed doorways with split boarded doors, and 2 shuttered loft openings beneath the eaves. The downhill gable end has a loft doorway, above which are ledges and pigeon holes in brick surrounds. The rear lean-to has an asbestos-cement roof.

The house has a slate floor to the entrance hall, leading to a close-string staircase. The R-hand room has a fireplace with its lintel removed, flanked by cupboard recesses. In the dairy are slate troughs.

In the cow house, the 6-bay collar-beam roof has iron bolts and is a C19 replacement of the original roof, perhaps when the pigeon holes were added. It retains stalls for horses, indicating that it was latterly used as a stables.
