Description
Dolwen is a two-storey, three-window house, with a later left bay, dating from the 19th century. It is constructed of whitewashed shaley rubble stone and has a slate roof with stone end stacks to the left and left of centre. A gabled porch with a yellow brick base supporting wooden openwork is situated far to the right, featuring an archway to the front and decorated barge boards to the gable. A four-pane wooden window sits to the left of the entrance, beneath a timber lintel. The upper storey has three three-light wooden casements with quarry glazing rising to the eaves; all windows have slate sills. To the right of the house, and without a butt joint, is a single-storey, three-door cow-house also under a slate roof. A planked door, likely leading to a feed passage, is positioned at the centre, flanked by split doors, all with timber lintels. A ventilation slit is located far to the left. The rear of the house has a long, single-storey lean-to offset to the left, with two-light wooden casements to its rear wall and left return. Similar casements are present in the lower storey of the main range, to the left and right of the lean-to. The rear of the adjoining cow-house features a doorway to the right of centre and one small window towards the left. A doorway is present in the north gable of the cow-house, which is partly built into the bank.
Attached to the left end of the house is a five-bay, half-timbered farm building with multiple purposes, and a slate roof. It has a high rubble-stone plinth, with the box panelling now largely open, although some sections retain weather-boarding and corrugated iron sheeting. The cart-shed bay at the left end has been partly rebuilt in slate blocks. To the right is a three-bay cow-house with a planked door leading to a feed passage. The flanking doorways no longer contain doors, allowing visibility into the interior. The outer bays contain wooden stalls at right angles to the length of the building, facing the feed passage. The roof features tie-beam trusses with curved struts. A stone wall divides this cow-house from the fourth bay to the left, also used as a cow-house, featuring two doorways for feed and animals, with stalls again transverse. The bay at the left end is a cart-shed, accessible via external stone stairs and a doorway in the south gable end. At the rear, the three-bay cow-house has doorways at either end, each inset and with a large timber lintel. The two bays to the right retain half-timbering and have no openings.
No access to interior was possible at the time of inspection.
