Chepstow Railway Station

Chepstow Railway Station is a small stone station building designed in the Italianate style. The exterior walls are made of roughly dressed stone arranged in regular courses, with bands, dressings, and quoins crafted from contrasting tooled ashlar. The building features a hipped roof, possibly with its original lead covering, and has wide overhanging eaves that are bracketed and boarded, creating a canopy. A blue brick stack is present.

The western entrance and eastern track elevations each consist of five bays. The windows are round-headed, featuring impost bands and bracketed sills, and the building has a battered plinth. Each of the projecting center bays has a round-headed doorway, flanked by wider intermediate bays with windows, and narrower recessed end bays. There is a window at the south end of the west elevation and a doorway in the south end bay of the east elevation.

At the south end, the station adjoins a wing with a hipped slate roof and boxed eaves, which includes two pairs of windows in the west wall and two round-headed doorways with windows in the east wall. To the north, there is a four-bay timber canopy from the 1870s or 1880s, featuring a backward sloping roof supported at the rear by a wooden boarded and brick wall and at the front by three fluted and reeded iron columns with decorated caps. This canopy is anchored into the 1850 building at the south end and incorporates a weighbridge.
