7 Best Garden Buildings That Don’t Need Planning Permission


What can I build in my garden without planning permission?

You can build a garden building or summerhouse without planning permission in the UK if it meets these conditions:

  • It’s positioned at the rear of your property (not the side or front).
  • It’s not on the grounds of a listed building.
  • In Areas of Outstanding Natural Beauty (AONB), National Parks, the Broads, or World Heritage Sites, any building over 20 metres away from the house must be under 10 square metres.
  • The building and other structures do not cover more than 50% of the land around your house.
  • It won’t be used as separate, self-contained living accommodation.
  • It’s single-storey with an eaves height of 2.5m or less, and a maximum height of 3m for flat roofs or 4m for pitched roofs.
  • If within 2 metres of a boundary, the whole building does not exceed 2.5 metres in height.

Different rules may apply to flats, maisonettes, and other buildings; always check with your local planning authority.
