In 1921, immediately after the launch of Craven A, Carreras launched yet more brands such as Wall Arms, Piccadilly and Turf. By 1927 the business had outgrown the Arcadia premises in City Road; the war had increased demand for cigarettes and, despite taking on additional London premises at Aldgate, Carreras had to find or create a new factory. In 1928, the famous Arcadia Works was opened in Mornington Crescent NW1, formerly a favourite residence of artists and writers. This building, which has become a major London landmark, was as revolutionary in its concept as it was unusual in its design. It was the first factory in Britain to make use of pre-stressed concrete technology, and the first to contain air conditioning and a dust extraction plant. The company was also the first to provide full welfare services for its employees. Such was the fame of the Arcadia Works that it was often visited by royalty, including the Duke of Windsor when he was the Prince of Wales, King George VI when he was the Duke of York, and the Duke of Kent. Many other important visitors from every part of the globe were entertained at Mornington Crescent. Dominating the entrance to the building were two large bronze cats. Cast at the Haskins Foundry in London, these versions of the Egyptian god Bastet were each eight feet six inches tall and stood guard over Arcadia Works until 1959 when Carreras merged with Rothmans of Pall Mall and moved to a new factory in Basildon, Essex. The cats were separated, with one making the short journey to Essex, while the other went to be displayed outside the Carreras factory at Spanishtown, Jamaica.
