Description

Dol-wen is a building that consists of two parts. The first part is a single-storey structure made of rendered stone, dating from the 16th century or earlier, which runs parallel to the road and contains the hall and inner rooms. It features a slate roof. The second part is a two-storey cross wing, built in the late 19th century, which replaces the earlier end bay. This wing is made of stone with brick dressings and has a half-hipped slate roof, containing a sitting room and dining room.

The entrance to the hall is through a boarded door, which has a 12-pane sash window and a casement window in the inner room. There are also two-paned dormer windows with raking roofs. The cross wing features a part-glazed door with a moulded canopy supported by cut brackets, along with 12-pane sashes on both the ground and first floors.

The original structure is separated from the cross wing by an axial fireplace that was inserted in the 16th century. This fireplace has orthostatic jambs and broach stops, along with a side oven. The building includes two complete cruck trusses, with the truss over the fireplace being the central truss of an open medieval hall. The blades of this truss have double hollow chamfers that stop at moulded knee braces, which rise to a slightly cambered collar. Above, cusped raking struts create side trefoils and a centre quatrefoil at the apex. The blades are tenoned and cut off for a half-tree ridge, and there are three tiers of chamfered purlins. The wallplate is morticed on the soffite for former wall framing.

The second truss, which is also embedded in the stone walls, is fully framed and forms a close-studded partition with a middle rail and end door openings that have chamfered round-headed frames. Above this, a centre post rises to the collar, which is half lap dovetailed from the hall side over the blades and has an intermediate rail below. Two chamfered axial beams support the inserted floor.
