Planning Permission Guidance

A Thaxters building will rarely, if ever, require planning permission or building regulation certification. Garden buildings fall within Permitted Development and are not subject to planning regulations as long as they comply with some basic criteria. In the rare case that it does we can advise a suitable course of action and help you with the process.

In short, as long as a garden building is behind the front elevation of the house and is no more than 2.5m tall at its highest, it can be built. A building can have a maximum roof height of 4m and a maximum eaves height of 2.5m providing it is more than 2m from a boundary but specifically can only be single storey.

The building is also specifically not allowed to be used as self contained living accommodation and cannot have a television antennae. It should be understood that Thaxters Timber & Forestry do not make buildings for this purpose.

There also strict rules about how of the area of a garden the building can take up. No more than 50% of the original designated garden space as the building first stood or as of 1st July 1948. This means that any extensions need to be factored into the equation should you want a large building in a small garden.

 

The following is taken from the Planning Portal website:-

 

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.

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.

Please note: The permitted development allowances described here apply to houses and not to:
