Permitted Development Rights

What is Permitted Development? How to get Permitted Development?

Not all building work requires planning permission. Home-owners often seek to create additional living space, adding significant value to their homes in the process. However, there are limits to what one can build under permitted development.

All works to a property that are considered development require planning permission. However, some development is permitted without the requirement to submit a formal planning application as it is granted automatically under Article 3 of the General Permitted Development Order 1995.

This means that you are able to make certain minor changes to your house without needing to apply for planning permission. These are your "permitted development rights" and are described in full in this guide. Permitted development rights are universal across all local authorities as they derive from a general planning permission granted by the government.

Permitted development rights are set out in Schedule 2 of the Town and Country Planning (General Permitted Development) Order 2008, otherwise known as "permitted development" (PD).

Please note: permitted development rights only apply to houses and do not apply to flats, maisonettes or other buildings. you will need full planning permission for all works to a flat or maisonette.

Permitted Development Rights

The rules of what is 'permitted development' changed with effect from the 1st October 2008.

Under the new regulations an extension or addition to your home is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:

  • No more than half the area of land around the "original house" would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation fronting a highway.
  • No extension to be higher than the highest part of the roof.
  • Maximum depth of a single-storey rear extension of three metres for an attached house and four metres for a detached house.
  • Maximum height of a single-storey rear extension of four metres.
  • Maximum depth of a rear extension of more than one storey of three metres including ground floor.
  • Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
  • Two-storey extensions no closer than seven metres to rear boundary.
  • Roof pitch of extensions higher than one storey to match existing house.
  • Maximum eaves height of an extension within two metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension no higher than existing house.
  • Materials to be similar in appearance to the existing house.
  • No verandas, balconies or raised platforms.
  • Upper-floor, side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.

On designated land* no permitted development for rear extensions of more than one storey.

On designated land no cladding of the exterior.

On designated land no side extensions.

*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.


In some areas of the country, known generally as 'designated areas', permitted development rights are more restricted. If you live in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Norfolk or Suffolk Broads, you will need to apply for planning permission for certain types of work which do not need an application in other areas.

Withdrawn Permitted Development Rights

You should also note that the local planning authority may have removed some of your permitted development rights by issuing an Article 4 direction. This will mean that you have to submit a planning application for work which normally does not need one.

Article 4 directions are made when the character of an area of acknowledged importance would be threatened. They are most common in conservation areas. You will probably know if your property is affected by such a direction, but you can check with the local planning authority if you are not sure.
