Notification for Prior Approval for a Proposed Larger Home Extension

This notification can be used by a household to notify a local planning authority of the intention to use the permitted development rights to build a single-storey rear extensions between 4m and 8m projection (on a detached house); between 3m and 6m in any other case. Extensions must be 4m or less in height. These temporary rights do not apply to Article 1(5) land (i.e. Conservation Areas) or SSSI.

If the Prior Approval Procedure is applicable to your proposal:

  • The Council must write to adjoining neighbours.
  • If no objection is received, we can formally confirm that Prior Approval is not required.
  • If an objection is received, we must then assess impact on residential amenity. We then decide whether the proposal can be granted accordingly having taken residential amenity into account.
  • Must assess impact on all neighbours not just the one who objected.
  • We can ask for additional information at this stage if necessary.
  • We have a 42 day deadline after which Prior Approval is deemed to be granted.
  • The extension must be completed by 30 May 2019 and the applicant must notify the Council of completion in writing.

There is no fee for this type of Prior Approval Procedure.
