Carreg Fawr is an estate farmhouse with farm buildings built c1870-5 as part of the general rebuilding of the farms on the island. There were 4 pairs of farmhouses and 3 single houses, this one, Plas Bach and the chapel house. Carreg Fawr and Plas Bach appear to be of slightly larger scale than the semi-detached farmhouses and may reflect higher status occupants.
