Decking

You are viewing guidance for England. To view guidance specific to Wales, please select the 'Welsh site' option from the top right of this page.

Planning Permission

Putting up decking, or other raised platforms, in your garden is permitted development, not needing an application for planning permission, providing:

  • The decking is no more than 30cm above the ground
  • together with other extensions, outbuildings etc, the decking or platforms cover no more than 50 per cent of the garden area.

Please note: the permitted development allowances described here apply to houses not flats, maisonettes or other buildings. View guidance on flats and maisonettes here.

Building Regulations

Building Regulations should be assumed to apply to every deck structure requiring planning permission.

If you are unsure about whether you are required to comply, you may wish to contact your local Building Control body.
