Description
The outbuilding at Glan-y-morfa is a single-storey structure built from locally sourced boulders mixed with white quartz. It features a graded slate roof that is set between raised and coped parapets, supported by double-ovolo moulded kneelers. The building has three bays and includes narrow, off-centre opposing doors with half-round arched stone heads. One of the doors is a 20th-century boarded door with a fanlight above it. The bay facing the road has a similarly constructed window opening, which contains a 20th-century glazed window. There are ventilation slits at two levels, as well as two additional slits in the gable end beneath a pitching door.
