Some cabin and timber structures can be installed in your garden and extended land areas without planning permission.

The new limits and conditions for permitted development came into effect on 1st October 2008.

  • No cabin above 4m high
  • If the cabin is over 30 square metres building control may be required
  • The cabin cannot be more than 50% of your garden area including any other extended work undertaken to increase your original building.
  • If the cabin is over 2.5m high it will need to be 2 metres from your boundary.
    The cabin has to be 1m from any boundary if less than 2.5m high and over 15 square metres
  • If under 15 square metres and below 2.5 metres the structure can be sited closer than the 1m building control ruling
  • Creative Living offers a free site survey where we can measure up and discuss your cabin options and choices
  • Below we have added a link to the government planning portal pages showing the planning and building control regulations


Planning Permission

Rules governing outbuildings apply to sheds, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structure for a purpose incidental to the enjoyment of the dwellinghouse.

Other rules relate to the installation of a satellite dish, the erection of a new dwelling or the erection or provision of fuel storage tanks.

Under new regulations that came into effect on 1 October 2008 outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits 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.

*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.


Building Regulations

If you want to put up small detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres.

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building is either at least one metre from any boundary.

In both cases, building regulations do not apply ONLY if the building does not contain any sleeping accommodation.
