You would need to apply for planning permission if the extension or the addition to your house does not meet the following limits and conditions:

[Rewording of: ‘Under new regulations that came into effect on 1 October 2008 an extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions’]

  • No 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 metres beyond the rear wall for an attached house and four metres beyond the rear wall for a detached house.
  • Maximum height of a single-storey rear extension of four metres.
  • Maximum depth of a rear extension of more than one storey of three metres beyond the rear wall including ground floor.
  • Maximum eaves height of an extension within two metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension no higher than existing house.
  • Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
