Do I need planning permission for a shed?


I’m building an outbuilding or annex or Shed, do I need Planning permission?

Outbuildings are considered to be within permitted development criteria on most cases. And are considered to be categories with other ancillary garden buildings such as:

  •  Shed
  •  Greenhouse
  •  Garage
  •  Swimming pool
  •  Pond
  •  Sauna cabin
  •  Kennel
  •  Enclosure (including tennis court)

It’s a great way of adding extra space which is separate from the rest of the house, normally granted via permitted development, subject to the following limitations and conditions:

  • No outbuilding on land forward of a wall forming the principal elevation.
  • Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
  • Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwellinghouse.
  • No verandas, balconies or raised platforms.
  • No more than half the area of land around the “original house”* would be covered by additions or other buildings.
  • In National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites the maximum area to be covered by buildings, enclosures, containers and pools more than 20 metres from house to be limited to 10 square metres.
  • On designated land* buildings, enclosures, containers and pools at the side of properties will require planning permission.
  • Within the curtilage of listed buildings any outbuilding will require planning permission.
