   Added to PlanIndex

The council has decided this application; the published outcome sits in the record above and the decision notice on the council portal carries the detail, including any conditions.

If permission was granted, work must normally begin within three years of the decision. If it was refused, the applicant can appeal within the statutory time limit or submit a revised scheme.

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.
