“Despite repeated amendment and consolidation the provisions enacted in 1945 remain essentially intact. They reflect a general legislative policy, formed in the very difficult economic conditions at the end of the Second World War but still continuing half a century later, to encourage industrial activity by according to industrial buildings advantages not accorded to shops and offices. But the precise extent of the advantages depends on the correct construction of the legislation, and in particular the terms of section 18 of CAA 1990 (definition of "industrial building or structure").”
