Prior approval for larger home extensions

The Town and Country Planning (General Permitted Development) (Amendment) (England) Order 2013 amendment introduces a number of temporary relaxations and/or new procedures for householder extensions,

Householder provisions

If you want to construct a single-storey rear extension that extends between 3 metres and 6 metres from the rear wall of the original house and you live in a terraced/semi-detached house, or between 4 metres and 8 metres from the rear wall of the original house if you live in a detached house, providing it does not exceed 4 metres in height, would not be to a property within a Conservation Area and would otherwise comply with the existing provisions of current Householder Permitted Development Rights.

If your extension falls within this criteria you must notify us at that you are intending to build this extension.

Make sure to include the details listed below, or complete and return this form and send it back to us.  The Government have created some guidance for applicants planning on applying for prior approval.

  1. the dimensions of the extension - length from the original rear wall; the maximum height; and the height of the eaves
  2. a plan showing the site and the proposed extension
  3. addresses of adjoining premises
  4. the developer's/applicant's contact address, and
  5. the developer's/applicant's email address

From 19 August 2019 the fee for this process will be £96.00.

  • we will then notify adjoining properties that you want to extend your property
  • they will be given 21 days to respond
  • if no objections are received at the end of the 21 day period, prior approval will not be required and you can then start your extension

 If an objection is received, then the Council will consider what impact the extension would have on adjoining properties.

  • if it is concluded that the extension would have an unacceptable impact on the adjoining properties then Prior Approval will be refused
  • if the impact is considered to be acceptable then Prior Approval will be granted

 Your extension cannot be started until we have notified you that the Prior Approval has been given, which must be issued within 42 days from the submission date.  If Prior Approval is refused then the applicant has a right of appeal to the Planning Inspectorate.
