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The applicant is free to submit a revised application at any time, and many withdrawn schemes return in amended form, so the site is worth watching if the proposal affected you.

Householder applications cover work to an existing house and its garden: extensions, loft and garage conversions, porches, outbuildings and similar alterations within the boundary of the home. They cannot be used to create a separate dwelling or change what the building is used for. Councils aim to decide them within eight weeks, and immediate neighbours are usually notified and given a chance to comment.
