Description
The Harbour Master's Office is a 2-storey building located by the quayside, featuring pebble-dashed walls and a slate roof with a skylight. The entrances to both storeys are situated in the left side wall facing Porth Bach. The lower storey includes a boarded door on the left side, next to which are stone steps leading to a first-floor boarded door. The upper storey has a 2-light small-pane casement window.
On the gable end facing the quay, the lower storey features a shallow canted oriel window with a fixed small-pane window and casements on the outer facets. The upper storey has a canted oriel with a 4-pane sash window. A later coped stone wall is attached to the right side of the gable end, and the rear of the building is built against the town wall.
Inside, the upper floor includes a window seat, while the interior also features window shutters and a small 19th-century round-headed iron grate.
