The farmhouse was probably newly built by the Roberts estate of Bryn Hall as it does not appear on the tithe map for Llanymawdddwy. The former Buckley estate was bought by the eminent London surgeon, Sir William Roberts MD FRS in 1878, who undertook many works of improvement to the buildings and living conditions in the district.


Built of rubble stone, with a slate roof. Two storeys, 3 bays aligned along the crest of a small hill. A symmetrical front faces W. Central part-glazed door with a deep stone lintel. The bays either side, and the three first floor windows are all 2-light 6-paned timber casements, stone lintels over the ground floor window openings. Deep gabled eaves to the gable end, which is clad in corrugated iron. Stacks to both gable ends with dripstones and necking courses. At the rear, a lean-to placed centrally, and two 2-light windows.


Not accessible at the time of inspection.
