Geilston Hall, Main Road, Cardross

Geilston Hall was built in 1889-90 by Honeyman and Keppie as a drill hall for the local rifle volunteers. The pale sandstone hall is set back from the road and is in a Collegiate Tudor style. There is a two-storey administration block at the west end incorporating a square tower with a crenellated parapet. The former instructor's accommodation is on the upper level, and is accessed by a stone forestair to the rear.

The single-storey hall has two gabled porches, each with a roll-moulded Tudor-arched doorpiece. Above each door is a cast stone plaques with the inscriptions 'The Geilston Hall' (to the west door) and 'Erected 1889 in memoriam J.T.G' (to the east door). There are three buttresses between the porches and arrow-slit air vents equally spaced between them. There are tripartite window openings with stone mullions and transoms, while the upper stage of the tower has round-headed timber window frames. The roof is of grey slate with roof lights along the ridge and there is a chamfered chimney stack with clay cans on the west side of the tower. A smaller (pre-1950) hall addition adjoins the building at the northeast corner.

The interior, seen in 2016, largely retains its 19th century character with timber panelled doors throughout. The top-lit hall roof structure has arch-braced timber trusses on stone corbels. There is a timber platform to the west end, grooved timber panelling to the walls and some ornamental ironwork detail. The south wall has three timber vents, where the wooden framing has been carved to mirror the shape of the stone corbels. The fireplace within the tower has a carved timber surround. The former armoury room on the ground floor to the north of the tower has a heavy door with a large metal lock and key. The smaller hall adjoining to the rear has a metal, A-frame roof structure. The former instructor's dwelling on the first floor level was not seen (2016).
