Cadw's description

Located approximately 20m to the south-west of Port House immediately to the north of Pont Penrhyn.

Probably built at about the same time as Port House, designed by Baxter, as part of the continuing development of Porth Penrhyn. A photograph of c1913 shows the building at the intersection of the Penrhyn Railway and the branch line opened in 1852 linking it with the Chester-Holyhead line; there is a small timber booth attached to the now blank west wall and a large ridge stack (now also gone) to the pedimented section.

Small single-storey building of rendered rubblestone or brick; hipped slate roof with deep eaves and pedimented section to west. East wall has boarded door to left and infilled window to right; multi-paned tripartite sash window in north wall; south and west walls blank except for plain cornice to pediment on latter.

Interior not accessible at time of Survey.

Included as an integral feature of the remarkable late C18 and C19 industrial port complex at Porth Penrhyn, the building has strong group value with the other structures here, in particular Port House and Pont Penrhyn.
