This article describes the use of glass-reinforced polyester (GRP) in Preston Bus Station in Lancashire, England, designed by Building Design Partnership (BDP) and completed in 1969. GRP was used both for concrete moulds that play a key role in enabling the construction of the building’s distinctive elevation, and for kiosks, signage and smaller fittings. A survey of articles shows that the use of GRP for concrete moulds enabled innovative and efficient construction and this practice continues to date. Some smaller fittings in GRP which were expected to be durable and maintenance-free have been modified, damaged, or removed, yet, others survive and are in a good condition. The legacy of the car park pay kiosks was to last as a prototype for a prefabricated sectional building system.
