Description
Dolaugwyn is a large house, originally dating to the 16th century, with significant additions and alterations in the mid 17th century and later. It is constructed of dressed stone with slate roofs and features stepped gables to both the original fabric and later additions.
The porch tower is a prominent feature and contains a segmental archway over the entrance, embellished with a decorative rebate. Above the arch is a shield, depicting a blue lion rampant within simple strapwork detailing, set within a recessed area formed by re-facing the stone. A four-light mullioned and transomed window with ovolo moulding, sits above this, illuminating a first-floor chamber. A second datestone reading “AC 1820” is positioned above. The second floor of the tower is slightly jettied, supported by a continuous shallow ovolo corbel course, and features a three-light mullioned window set within a stepped gable. To the west of the porch, two windows are visible, one now blocked, both featuring stone canopies supported by brackets.
The main range of the house also incorporates four-light mullioned and transomed windows with stone lintels and similar stone canopies. Above the porch, the attic floor is raised behind a stepped gable, showcasing a three-light window. The southwest gable end has four-light windows to the ground and first floors, but two two-light ovolo-moulded windows to the attic floor. The gable stack has been rebuilt. The rear of the original section presents a three-storey, stepped-gabled tower, likely the original stair tower, and the original ground and first-floor windows have been replaced with timber-framed paned windows. An external stack is located on the main hall.
The mid 17th century additions include a square drawing room block with four-light windows mirroring the earlier design and a stepped gable facing northwest, and a stack on its east wall. A larger square stair tower with an asymmetrical stepped gable was also added, although its windows were later altered to timber sash windows. Subsequently, a rounded structure was built to connect the original stair tower to the service wing, and a single-storey service wing was added to the south side, further extended to the south by a lower structure with twin gable stacks.
The interior, which wasn't accessible at the time of inspection, is reported to contain a later passage leading from the hall to the gable stair, allowing access to the drawing room and kitchen. A good, open-well 17th-century staircase remains. Decorative and heraldic figures dated to the 17th century are said to be in their original positions.
