Section 26D of the Planning (Listed Buildings and Conservation Areas) Act 1990 (“the Act”) provides that a local planning authority may make a local listed building consent order which grants listed building consent for works of any description for the alteration or extension (but not demolition) of listed buildings of a specified description or in a specified part of the authority’s area. Section 26F provides that, in considering whether to make a local listed building consent order, the local planning authority must have special regard to the desirability of preserving listed buildings of a description to which the order applies, their setting or any features of special architectural or historic interest which they possess.
