In this Act the expression “industrial hereditament” means a hereditament (not being a freight–transport hereditament) occupied and used as a mine or mineral railway or, subject as hereinafter provided, as a factory or workshop: F2

For the purposes of this Act any place used by the occupier for the housing or maintenance of his road vehicles or as stables shall, notwithstanding that it is situate within the close, curtilage or precincts forming a factory or workshop and used in connection therewith, be deemed not to form part of the factory or workshop, but save as aforesaid, the expressions “factory” and “workshop” have respectively the same meanings as in the Factory and Workshop Acts, 1901 to 1920.

Where two or more properties within the same curtilage, or contiguous to one another, are in the same occupation and, though treated as two or more hereditaments for the purposes of rating and valuation by reason of being situate in different parishes or of having been valued at different times or for any other reason, are used as parts of a single mine, mineral railway, factory, or workshop, then, for the purposes of determining whether the several hereditaments are industrial hereditaments they shall be treated as if they formed parts of a single hereditament comprising all such hereditaments.
