Planning Permission for Timber Garden Buildings

Planning Permission for Timber Garden Buildings

Permission for Timber Garden Buildings is something we are regularly asked about at Cambridge Timber Buildings. Planning Permission for Timber Garden Buildings is not necessarily a requirement for certain buildings and structures being designed, manufactured and installed in your garden or on land surrounding your property. All timber garden structures, including garden sheds, summerhouses and garages are subject to planning permission rules; however, the good news is that the majority of our buildings won’t actually require planning permission for installation. This is providing the building or structure conforms to certain limitations outlined by the Planning Authority. If the Garden Building or structure does not fit within these limitations then a planning application will need to be submitted. If this is the case Cambridge Timber Buildings can do this for you.
Most clients require their chosen Garden Building to be manufactured and installed as quickly as possible. This is why we design the majority of our buildings to comply with the regulations set out by the local planning authority.

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 dwelling/house. 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 dwelling/house.
  • 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 not flats, maisonettes or other buildings. View guidance on flats and maisonettes here.

If you want to put up a garden building, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation. 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 contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed of substantially non-combustible materials.
