The much altered late seventeenth-early eighteenth century west range of the service court at Cefnamwlch.
A single storey lofted range with rubble stone walls and a slate gabled roof. The range is shown divided into three sections on early OS County series mapping (Caernarvon. XXXIX.6 1889). The centre section, now fitted as a garage, is thought to have been the coachhouse, with a stable on the south and a service building on the north. The stable section has two windows set in lunettes.
