Guides for the applicant who runs planning applications in England and Wales: what a section 73, an outline, a retrospective and a change of use application are, what the use classes and class E mean, what an application costs and how long it takes, how a refusal is appealed, what a lawful development certificate proves, and what the statements argue.
