This application is at appeal, which passes the decision from the council to the national planning inspectorate, or in Scotland usually to a local review body first. The appeal considers the scheme afresh against the same policies.

Anyone who commented on the original application is normally notified and can comment again within the appeal deadline. Appeal decisions take months rather than weeks, and the outcome replaces the council's decision.

A full application seeks permission for a complete, detailed proposal in one go: siting, design, access and landscaping are all fixed at this stage. It is the standard route for new buildings, conversions and changes of use. The statutory target is eight weeks for smaller schemes and thirteen weeks for major development, though complex cases often take longer by agreement.
