Description

11 High Street is a 16th or 17th century timber-framed house that has been partially rebuilt and refaced in rubble stone. The building has two storeys and is aligned downslope, with its gable end facing the street. It features high rubble base walls, and the front door is accessed via six steps set between flanking rubble walls topped with coping slabs. The gable end displays exposed timber-framing with tall, thin panels, and a queen strut and collar roof-truss. A distinctive stone tiled pentice roof serves as a weather shield for the large projecting beam ends, which are pegged to the bresummer beam resting on the rubble base wall. Notably, the upper floor does not jet out over the beams, which is an unusual arrangement. The roof is covered in stone tiles, and there is a massive external rubble stack with offsets and a brick upper section on the right-hand side wall. A small gabled section of roof extends from the main ridge to join the upper part of the stack, which also includes large ashlar blocks that may have been reused from the nearby castle site.

The front door features a 19th-century chamfered door-frame and a boarded door. The front section windows are small-paned iron casements set in chamfered timber frames with original catches and stays, while the rear section windows consist of modern casements and 19th-century sashes.

The rear part of the house and the adjoining outbuildings have a lower roof-line made of iron. One outbuilding contains large flat-section joists with wide floorboards that are pegged through to them. Some timber-framing is visible but obscured by plaster and wallpaper. Inside, large chamfered wall-posts project into the rooms. The front room features a wide-chamfered transverse beam, with one end resting on a stone corbel. In the room above, there is a stone fireplace with moulded jambs, which is likely a reused feature.
