How Big Can I Build a Shed Without Planning Permission?

Whether buying a new house or adding to your existing home you may want to know what restrictions there are when it comes to garden outbuildings and just how big can you build a shed without planning permission.

“How big can I build a shed without planning permission?”, is a frequent question from home owners and buyers looking to add to their garden.

The relaxation of planning permission laws has made it much easier to determine which projects can be undertaken without the need to go through the whole planning process.

In regards to garden sheds there are a number of criteria that need to be met in order to avoid requirement to request a planning permit:

  • Sheds are 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.
  • If the shed lies within 2 metres of your boundary then the maximum height is a total of 2.5 metres
  • No more than half the area of land around the “original house”* would be covered by additions or other buildings.  This means if you have an already extended house and a small garden then the size of your shed will be quite restricted.
  • 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.

*The term “original house” means the house as it was first built or as it stood on 1 July 1948 (if it was built 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.
