Girvan Station Including Signal Box

Girvan Station, including the signal box, was built between 1946 and 1951. It is a streamlined, single-storey railway station featuring a flat roof and constructed from red brick with horizontal bands of cream-coloured faience. The entrance has paired doors that have been replaced, with a window between them and a striped terrazzo step. A low, broad curved canopy projects beneath a raised pediment. The station has advanced shallow curved bays on either side, each containing three windows, while the outer bays have two windows. There is a long range to the south with twelve windows forming a band of glazing. The flat roof has overhanging eaves, and some sections, particularly on the trackside, are likely later additions. The base course is painted red.

On the east (trackside) elevation, there are paired doors (also later replacements) with glazing between them, and advanced shallow curved bays, with the left bay featuring six windows and the right bay having three windows plus a ticket hatch. The long range to the left has an irregular arrangement of windows and doors. The original metal-framed hopper-type windows have lying-pane glazing, predominantly with twelve panes and four-pane upper sections.

The interior, partially seen in 2004, retains some original features, including a terrazzo floor and a ticket hatch in the waiting room.

The signal box, built in 1893 for the Glasgow and South Western Railway Company, has undergone later alterations. It is a large, nine-bay (formerly seven-bay) rectangular-plan structure with a piended grey slate roof and horizontal timber weather-boarding painted white. There is a timber forestair and entrance to the operating room at the eighth bay, and a brick chimney projection at the rear. The windows were replaced in 2012 with non-traditional designs.
