   Awaiting decision

   Decision expected by 1 April 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

The published feed does not show a live status for this application, which usually means the council register holds more recent detail than the copy PlanIndex receives.

The council portal linked on this page carries the authoritative version, including the documents, any consultation deadline and the decision once made. PlanIndex refreshes its copy of the register on a daily cycle.

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.
