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.
