Built in the Brutalist architectural style between 1968 and 1969, designed by Keith Ingham and Charles Wilson of Building Design Partnership with E. H. Stazicker, it has a capacity of 80 double-decker buses, 40 along each side of the building. Some claim that it is the second largest bus station in Western Europe.[1] Pedestrian access to the Bus Station is through any of three subways, one of which links directly to the adjacent Guild Hall, while the design also incorporates a multi-storey car park of five floors with space for 1,100 cars. It has been described by The Twentieth Century Society as "one of the most significant Brutalist buildings in the UK".[2]

The distinctive curve of the car park balconiesThe building's engineers, Ove Arup and Partners, designed the distinctive curve of the car park balconies "after acceptable finishes to a vertical wall proved too expensive, contributing to the organic, sculptural nature of the building. The edges are functional, too, in that they protect car bumpers from crashing against a vertical wall. The cover balustrade protects passengers from the weather by allowing buses to penetrate beneath the lower parking floor."
