Creigiau Duon

Creigiau Duon is a two-storey farmhouse with an attached agricultural range. It is constructed of coursed rubble masonry, with the house featuring roughly dressed blocks of stone, large stones used as quoins and lintels. The roof is slate, topped with stone gable stacks that have capping. The main elevation of the farmhouse faces east towards the road and consists of a three-window range with a central doorway, while the openings are offset to the right (north). The windows are two-light timber casements, with the first-floor windows positioned under the eaves.

At the rear (west) of the left (south) gable return, there are four-pane casement windows on both the ground and first floors, along with a single pitch roofed porch leading to a partially modernised service wing. Adjacent to the service wing is a linear agricultural range, likely a cowhouse, which features ventilation slits located under the eaves along the lateral walls. At the right (east) end of this range, there is a boarded door and a pitching or loft door situated above in a gabled dormer. To the left, there is another door, and a third door is located at the far left end of the range. A modern window has been inserted into a partially blocked doorway towards the center of the range.

The interior was not inspected during the survey conducted in June and July 2003.
