Description
Penrallt is a single-storey cottage range that features a single-storey wing added at right angles to the rear, creating a T-shaped plan. The building is constructed from local stone and is limewashed. It has a roof made of small old slates that are grouted. There are gable stacks on both the cottage and the former cowhouse, with the large stack at the left (east) end of the cottage likely serving an inglenook fireplace. The original cottage is located at the right (west) end and has two windows offset to the right, with a doorway situated between them. There is a lean-to addition at the west end. The former cowhouse is to the left and now features a door on the right (west) side and a window on the left. The windows are 4-pane hooded sashes with slate sills, and the doors are modern boarded types.
