Planning

Planning drawings are required in the UK if you proposed to build on land, or change the use of land or buildings**. Burlens will survey your existing site and produce a detailed, to-scale representation of the existing site and proposal. We endeavour to deposit onto paper you exact requirements and will assist and advise wherever necessary. Once you’re happy with the draft proposal we then progress to completing the drawings and all other relevant forms and documentation necessary for the local authority planning approval.

The following information is for guidance only and is not a definitive interpretation of the Planning Act. If in doubt you should contact your Local Planning Department for advice before undertaking any works to your property.

From 1 October 2008 an extension or addition to your home will be considered to be permitted
development, not requiring an application for planning permission, subject to the following limits and conditions:

  • More than half the area of land around the “original house”* would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation fronting a highway.
  • No extension to be higher than the highest part of the roof.
  • Maximum depth of a single-storey rear extension of three meters for an attached house and four meters for a detached house.
  • Maximum height of a single-storey rear extension of four meters.
  • Maximum depth of a rear extension of more than one storey of three meters including ground floor.
  • Maximum eaves height of an extension within two meters of the boundary of three meters.
  • Maximum eaves and ridge height of extension no higher than existing house.
  • Side extensions to be single storey with maximum height of four meters and width no more than half that of the original house.
  • Two-storey extensions no closer than seven meters to rear boundary.
  • Roof pitch of extensions higher than one storey to match existing house.
  • Materials to be similar in appearance to the existing house.
  • No verandas, balconies or raised platforms.
  • Upper-floor, side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
  • On designated land* no permitted development for rear extensions of more than one storey.
  • On designated* land no cladding of the exterior.
  • On designated* land no side extensions.

* The term “original house” means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

* Designated land includes national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.
