Ty Gwyn with Davey Jones' Locker Cafe

Ty Gwyn with Davey Jones' Locker Cafe is a rectangular first-floor hall block built of uncoursed rubble and topped with a slate roof. The stone-coped gables feature moulded kneelers, with the western gable having a squat end chimney. The eastern gable end has a vernacular Tudor-arched entrance leading to the lower floor, which includes a deeply recessed modern glazed door. Above this entrance is a modern recessed 9-pane sash window. The long southern side has raised access to the upper floor, with a plain entrance featuring a nearly flush modern boarded door and two small flanking slit-windows. In front of the upper southern side is a walled forecourt with stone steps leading up at the western end. This raised forecourt is situated above a much-altered single-storey addition that runs the entire length of the building, featuring three modern 6-pane windows on the southern side and a modern entrance with a boarded door set back slightly from the main gable on the eastern face.

Inside, the upper hall has seven bays with chamfered collar trusses arched to the wall plate and tenon purlin construction. Two trusses on the northern wall at the western end are supported by rough stone corbels. There is an apparently contemporary segmentally-arched fireplace on the western wall, which is currently obscured as of autumn 1994. The lower room, originally used for service, has stopped-chamfered ceiling beams, some of which seem to be original. There is a primitive end fireplace on the western side, opposite the entrance, featuring a rough segmental arch and hewn rock flanking it on both sides, giving an impression of battering. The northern wall has two blocked window embrasures, a blocked entrance, and to the right of the fireplace, a crude niche, all likely added later. Additionally, there is a further blocked window opening in the southern wall, and a rock-cut basement is located at the eastern end.
