John Laing Construction Ltd was one of the main contractors on the site, starting work in June 1968 with the construction of the new process and bottling stores. The Silberkuhl roof on the bottling store was designed to give the greatest possible working space without obstructing the production line. Measuring 230 ft by 200ft, it was the largest span in Britain when it was built.
