With the onset of WWI, supply from France ceased and the new factory at Park Royal was used to produce aircraft and engines
Eventually Park Royal had 5,800 employees at its wartime peak. Berwick had planned the new factory with post-war car production in mind and assuming that, after the war, production of the Sizaire-Berwick car would be undertaken in England. Coachbuilding was also carried out on this site (coachbuilders working there included Webb, Park and Ward, both to later have their own coachbuilding firms).
An agreement had been made with the Austin Motor Company during the war to fit bodywork to some Austin models at Park Royal.
