Description
Carnau is a two-storey building dating from the 18th century, constructed of rubble stone with a slate roof. It features a tall squared end stack on the right, adorned with decorative oversailing courses. The building has small, two-light timber casement windows, likely in their original openings.
Carnau showcases high-quality 18th-century features and considerable structural ornamentation. Inside, there is a large open fireplace with a chamfered timber lintel and a later brick-lined bread oven. The interior includes chamfered and scroll-stopped beams, exposed joists, and moulded brackets that support the beam ends. Substantial stud-wall partitions are present, along with chamfered and moulded door frames. One ornate timber door head has been reset in a now-blocked doorway in the rear wall. The first-floor door frames feature chamfered edges with mason's mitres. Heavy boarded doors are hung on gudgeon pins, and some original window openings have chamfered and stopped lintels with scratch moulded cills. An unusual framed staircase is notable for its panelled string with lozenge decoration, scratch moulded newel posts and handrails, flat barley-twist balusters, and carved brackets on the underside.
