Description
Llyswen is a Grade II* listed building featuring a three-panel high timber frame with corner braces that have been reduced to small angle reinforcements. The inner room bay displays close studding and shows signs of an applied window sill to a blocked opening leading to the dairy. The rear wall and west gable have largely been replaced with brick, while the east gable showcases decorative angled bracing at the apex.
An added two-storey porch is open to the front and features four square balusters on the upper side walls. The upper floor jetties out on all three sides, supported by moulded jetty plates on leaf-carved scroll brackets. The porch has decorative quadrant small panel framing, and the gable bressumer is intricately carved with a leaf design. There is a canted oriel window with an applied moulded sill, and the corner posts are adorned with carvings of hanging ropes. Inside the porch, there is an eight-panelled contemporary door on its original hinges. The front elevation includes two and three-light timber windows with iron casements, while the rear has a 20th-century door from the hall and three small gabled dormers.
Inside, the main hall features a ceiling divided into nine bays by deeply chamfered beams with long ogee stops, with joists laid in alternating directions. There is a large fireplace, which may have replaced an earlier timber-framed version, along with a stair located at the rear. A post and panel partition separates the inner rooms, with doors at each end, one of which shows evidence of a shaped head. The inner rooms are further divided by another post and panel partition, and there are battened and boarded oak doors throughout.
