  • any building or works not designed for agriculture
  • the construction, extension or alteration over
    1. 465 square metres in area, or

  • development which is within 25 metres of a metalled trunk or classified road
  • the construction or carrying out of any works to a building uses, or to be used, for intensive livestock accommodation or storage of slurry or sewage sludge where that building is within 400m of a "protected building." A protected building is a building normally occupied by people, but does not include buildings forming part of a working farm or certain special industrial buildings.  

Prior notification

Anyone intending to build or significantly alter/extend farm or forestry buildings or alter or form a new private way is required to notify the planning authority of their intention to carry out such development. This notification applies to the exercise of permitted development rights only i.e. to development for which planning permission is not required.
