A stone-built farmhouse of medieval origin remodelled in the C17th/C18th. The house occupies a sloping site on a natural shelf on the north side of the Dulas valley. The medieval phase is represented by a single cruck blade which apparently survives in the partition between the kitchen and entrance passage. The present farmhouse has a three-unit plan of characteristic C17th/C18th type with a central entrance and dairy set between upper kitchen and lower parlour, both heated by end chimneys. The spine beams in the kitchen have a three-inch chamfer and a curved stop. The house was refenestrated in the C19th/20th and a carthouse and granary added at the lower end. During recent renovation work the lintel of the parlour window was removed and found to be the head of a three-light timber window with rectangular mullions. Associated farmbuildings include a fine four-bay barn range with oak trusses.

The farmhouse became derelict when the farm was bought by the Forestry Commission. Mr Hywel Lewis, the last farmer of Cae-heulon, was featured in Y Cymro 16 Mai 1952. The house was subsequently restored by Mr & Mrs Morgan.

[Additional:] A site visit confirmed the correctness of the initial account. Caeheulon has a marked platformed siting with the upper end set into a bank and is probably late-medieval in origin. However, the present house has a seventeenth-/eighteenth-century three-unit plan with a central service-room and stair bay set between upper kitchen and lower parlour. The partitions between these rooms were originally of post-and-panel type with broad chamfered panels, now mostly removed but with a fragment surviving at first-floor level in the lower partition truss. The trusses are of interrupted tie-beam type. The upper partition truss has distinctive cruck-like curved principal rafters. These may be reused cruck blades although there are no obvious indications of reuse. All the beams have curved stops, somew with fillets, including the very substantial kitchen fireplace beam and several joists. The available detail (plan, post-and-panel partitions, moderately chamfered spine beams) suggest a date of c. 1700 or somewhat earlier. In a third phase the eaves were raised on the front elevation only; the roof-raising line is clearly visible in the upper gable. The C19th stair probably belongs to this phases. The substantial barn range, broadly contemporary with the house, needs further investigation.
