Planning permission - outbuildings and structures

​Planning permission is not normally needed for outbuildings, although there are some exceptions.

​In many cases outbuildings are considered to be permitted development, not requiring an application for planning permission. However you will need to apply for planning permission for some cases, for example:

  • outbuildings and other additions exceed 50% of the total area of land around the original house. Sheds and all other outbuildings and extensions to the original house must be included when calculating this 50% limit
  • the buildings are forward of the principal elevation of the original house
  • the building is more than single storey, or its eaves exceed 2.5 metres, or it exceeds 4 metres at ridge height where the building has a dual pitched roof, or exceeds 3 metres at ridge height in any other case
  • the new building itself is a separate, self contained, living accommodation
  • the building is more than 2.5 metres in height and it is within 2 metres of the property boundary
  • containers, such as those used for domestic heating purposes, would exceed 3,500 litres
  • the building is built to the side of the house, and it is on a designated land*
  • the building is within the grounds of a listed building
  • for sites within the Cotswold Area of Outstanding Natural Beauty, the total area to be covered by any outbuildings more than 20 metres from ANY WALL of the house would exceed 10 square metres

*Designated land includes national parks and the Broads, areas of outstanding natural beauty, conservation areas and world heritage sites.
