Station Building, Mostyn Station

Mostyn Station is a station building designed in the Italianate style, dating from the 19th century. It features a two-storey, five-bay entrance front with advanced outer bays. The structure is built from dark red brick with freestone dressings, some of which are painted, and includes terracotta panels. The building has high moulded and stepped eaves and an almost flat roof, topped with four tall brick stacks that have bracketed cornices and one pair of original chimney pots.

The openings have square-headed moulded architraves, but the window glazing is now missing or boarded over; these were originally double-hung sash and casement windows with paired central glazing bars. The outer bays are accented with banded freestone quoins, and the windows in these areas are linked vertically by ornamental panels, each featuring a coronet above a cartouche head of Lord Mostyn, with parchment scroll inscriptions below. Above the central doorway, which is now boarded but once had double panelled doors, there is a wide terracotta panel adorned with scrolls and foliage. The ground floor originally had a lean-to iron canopy, with surviving cast iron openwork brackets that display scrolled decoration.

On the platform elevation, there is a straight two-storey, five-window front, with one-storey pavilions at the outer angles, a central doorway, and similar detailing as the entrance front. This side also had a long iron canopy, with decorative brackets still in place. The pavilions feature parapets and detailing consistent with the rest of the building. There is a segmental-headed doorway on the inner side of the west pavilion, two small windows on the platform front, and a door and window on the west side. The west end of the main range has a two-window, two-storey configuration, with narrower lower lights. The east end mirrors this with a single window above flanked by smaller lights that are 20th-century insertions. The entrance front of the east pavilion has a planked door, and there are two doorways on the east side.

Access to the interior was not available at the time of inspection in March 2001.
