1. Currently roofless stone farm building, a Welsh longhouse measuring 20m x 5m shown partly roofed on the 1st edition Ordnance Survey map. The building is detached and sited in a sheltered northern hollow below the higher plateau on which the main 19th century Island Farm stands. The construction of the building is of rough stone and is a smaller, simpler structure than the main farm. Its character and position suggests it may be a predecessor to the main farm.
