TOWN AND COUNTRY PLANNING, WALES
This Order amends, in relation to Wales, the Town and Country Planning (Use Classes) Order 1987 (“the Use Classes Order”), which specifies classes for the purposes of section 55(2)(f) of the Town and Country Planning Act 1990. A change of use of a building or other land does not involve development for the purposes of the Act if the new use and the former use are both within the same specified class.
