Planning Permission Guide

Do I Need Planning Permission For A Shed?

Normally Planning Permission or Building Regulation approval is not required provided that:

  • Sheds and greenhouses do not cover more than half of the area of the garden; not including the area occupied by the house.
  • It contains no sleeping accommodation and the floor area does not exceed 15 square metres.
  • No point is less than one metre from a boundary.
  • It is not more than 3m high for a flat roof, or 4m with a ridged roof.
  • Overall height from ground level to ridge must not exceed more than 2.5 metres within a 2 metre range of any boundary. A building with overall height exceeding 2.5 mtrs in height and placed within 2 metres of any boundary will require planning permission.
  • Height of the eaves must not exceed 2.5 metres.
  • No part projects beyond any wall of the house that faces a road.
  • The outbuilding is for use only by those who occupy the house.
  • A Log Cabin should be more than 5 metres from the main dwelling and up to 50% of the remaining garden can be utilised with this type of building.
  • No verandas higher than 30cms from ground level.
  • Building Regulations do state that structures built of combustible material (i.e. a wooden shed) must be at least 2 metres from the main house.
  • If at all in doubt contact your local authority for clarification. No charge will be made if no planning permission is required.

Note that you will need planning permission if you intend to use the shed as a bedroom and/or you wish to install a toilet in it; or if you intend to run a business from it (as opposed to using it simply as a home office).

The shed should be sited at least 1 metre from any boundary (e.g. your garden fence) and cannot take up more than 50% of your garden space.

Further restrictions apply if you live in:

  • a Conservation Area
  • an Area of Outstanding Natural Beauty
  • a National Park

where planning permission may be required for any kind of shed structure.

Building Regulations

A shed with a floor space of less than 15 square metres would not normally have to comply with building regulations if it does not contain sleeping accommodation. Some restrictions do apply to sheds between 15 and 30 square metres. Of course normal safety standards have to be adhered to, particularly regarding any electrical connections.

Sheds In Woodlands

If you are lucky enough to own a bit of woodland, you may want a shed to store tools and equipment. For any permanent structure, you should seek planning permission. For details and advice, and further useful comments in the accompanying correspondence from woodland owners, see www.woodlands.co.uk/blog/practical-guides/woodland-sheds.

Please note that the content on this page is no way binding and all planning permission decisions are dependent on local authorities. Please contact your local council for more information.
