A module 30 feet by 30 feet based on the prefabricated buildings introduced by British Railways in 1964. One of a series with the suffix 'a' or 'b' which can be placed together as desired by the user to make station buildings of any size. This is the central booking hall and should be used with a '1a' or '2a' module on either side. Unlike my earlier modernisation plan structures, this building is fully glazed.
