Abergavenny Railway Station, including down platform building and footbridge

The main building on the town side is built of pink semi-ashlar sandstone with natural slate roofs and stone stacks. The secondary building is stone with a timber-framed front and a natural slate roof. The footbridge joining the two is cast and wrought iron and steel. Main building: Single depth central entrance plan. Plain Italianate style. Two storeys, five windows, 1 : 3 : 1, with the outer bays set slightly forward, additional single storey pavilions at either end built as conveniences and probably parcels office (now ticket office). Ground floor windows and centre door are round headed, panelled doors and 3 over 3 pane sashes, all with raised surrounds with imposts and keystone. Projecting canopy with fretted valance over three main entrance bays. Plat band between floors. First floor windows have 3 over 3 pane sashes with segmental arched heads with keystone. Timber dentil eaves brackets, hipped roof with two ridge stacks. The end pavilions have been more altered, particularly the left-hand one which has a C20 added first floor. The platform side is similar, but has a canopy to all five bays. The ground floor openings are partly masked by the raised platform, the original height for which is seen by the ticket office. The side pavilions are again more altered. Secondary building: This is on the southbound platform. Single storey. The platform elevation is recessed below a deeply projecting canopy. Three bays, central door flanked by windows, posts, then central windows with panelled dado beneath of nine panels. Hipped roof carries a fretted valance over the platform. Footbridge: Cast iron columns of typical GWR design support the stairways and the two spans. The span over the running tracks has been replaced by a steel plate-girder of utilitarian design during the BR period in the late C20, but the span over the now removed by-pass freight lines is the wrought iron lattice girder original.

The ground floor rooms of the main building have been altered and retain no visible historic features. Upper floor not seen at resurvey. Interior of secondary building is entirely plain.
