   Added to PlanIndex

Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.

Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.

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.

  Non-material amendment for Prior Approval ref 00590/3-8/PA2 and Planning Permission ref 00590/3-8/5 were conditional upon the submission and approval of a Car Park Management Plan. The CPMP dated 18/10/19, which was subsequently approved, detailed the strategy in regards to electric vehicle parking and specifically, the approach to provision of active and passive charging facilities. With this submission of an updated CPMP, we are seeking to amend the approach to future upgrades of passive parking spaces. This process this was previously to be facilitated and funded by the applicant, however the development is now controlled by a management company who will be responsible for actioning any future upgrade requests and with the cost to be borne by the resident (as is industry norm).
