What withdrawal means
The process from here
The applicant withdrew this application before the council decided it, so it carries no planning weight and no fee refund is automatic. Withdrawal often follows officer feedback that a refusal was likely.
The applicant is free to submit a revised application at any time, and many withdrawn schemes return in amended form, so the site is worth watching if the proposal affected you.
About full applications applications
How this application type works
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.
