Pirrie Hall at Old West Kirk, Campbell Street, Greenock

The Pirrie Hall, completed in 1925, was built by the Harland and Wolff Shipping Company. This single-storey church hall has a rectangular plan, a gabled outshot, and a steeply-pitched slated roof with overhanging eaves. It is constructed from squared and snecked cream sandstone rubble with ashlar margins, featuring a high base course and triangular skewputts. The hall is situated to the southwest of Old West Kirk.

The entrance features 2-leaf timber doors set within a roll-moulded and four-centred arched architrave. The windows have ashlar mullions, with larger windows in the gables also having ashlar transoms. The windows are multi-pane and leaded, with some including top-opening panes. The rainwater goods are made of cast iron, and the gutters are supported by decorative brackets. The interior of the hall, as seen in 2016, boasts an elaborate open kingpost timber ceiling with rafters that spring from stone corbels.
