Geilston Hall, Main Road, Cardross

Geilston Hall, built in 1889-90 by Honeyman and Keppie, served as a drill hall for local rifle volunteers. The building, constructed from pale sandstone, is set back from the road and designed in a Collegiate Tudor style. At the west end, there is a two-storey administration block featuring a square tower topped with a crenellated parapet. The upper level of this block housed the former instructor's accommodation, accessible via a stone forestair at the rear.

The single-storey hall includes two gabled porches, each with a roll-moulded Tudor-arched doorpiece. Above the west door is a cast stone plaque reading 'The Geilston Hall', while the east door bears the inscription 'Erected 1889 in memoriam J.T.G'. Between the porches, there are three buttresses and arrow-slit air vents spaced evenly. The hall features tripartite window openings with stone mullions and transoms, and the upper stage of the tower has round-headed timber window frames. The roof is covered with grey slate and includes roof lights along the ridge, along with a chamfered chimney stack with clay cans on the tower's west side. A smaller hall addition, built before 1950, is attached to the northeast corner of the main building.

The interior, as observed in 2016, largely maintains its 19th century character, featuring timber panelled doors throughout. The roof structure of the hall is top-lit and supported by arch-braced timber trusses resting on stone corbels. There is a timber platform at the west end, with grooved timber panelling on the walls and some ornamental ironwork details. The south wall includes three timber vents, where the wooden framing is carved to match the shape of the stone corbels. The fireplace in the tower has a carved timber surround, and the former armoury room on the ground floor, located to the north of the tower, features a heavy door with a large metal lock and key. The smaller hall at the rear has a metal A-frame roof structure. The former instructor's dwelling on the first floor was not accessible during the 2016 visit.
