Garden buildings are subject to the same planning permission rules as other types of outbuildings and ancillary garden buildings, but not all will require planning permission. Please read our updated article Planning Permission for Sheds for more in-depth information.
Below are listed the limits that a garden shed or other building must fall within to then not require planning permission. Its worth noting that these planning permission rules apply to our greenhouses, timber garages, garden studios, garden rooms, garden offices and many other types of structure.
Under new regulations that came into effect on 1st October 2008, sheds are considered to be permitted development, not needing planning permission, if they meet the following criteria:
- The shed is not to be forward of the principal elevation fronting a highway - In English, not closer to the road than the house itself.
- 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 2.5 metres within two metres of a boundary.
- 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 the 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. - If your house is listed, you will need to seek planning permission.
* The term “original house” means the house as it was first built or as it stood on 1st July 1948 (if it was build 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.
