Description
Bryn Brochan is a single-storey cottage that includes an attached cowhouse at one end and a now-ruined outhouse at the other end, built along the boundary of the plot. The cottage is constructed from rubble and finished with coloured limewash, featuring small slate roofs that are bedded and grouted. It has end chimneys, with a large stack on the right side. The openings are offset to the right, with a doorway located between two 12-pane sash windows. The cowhouse on the right has a central door flanked by two small windows, one of which is partially blocked. There is a stack on the right gable, next to the ruins of a pigsty. The outhouse on the left side of the dwelling is now roofless and has a single doorway at the front and a small fixed pane window at the rear.
At the time of the survey, the building was in poor condition. The internal layout of the dwelling has been altered by the addition of a partition that divides the original main space, creating a small room to the left of the doorway. However, the principal division remains as one main room with a major fireplace, which has been altered, and a smaller secondary room that is still identifiable. The secondary room was likely heated at one time, but its fireplace is now blocked. It is said that the cottage had a painted calico ceiling and access to a loft, but neither feature survives today. Inside the cowhouse, there is also a fireplace, indicating that it may have been used for domestic purposes in the past.
