You can make certain types of minor changes to your house without needing to apply for planning permission. These are called “permitted development rights” and are described in this guide. They derive from a general planning permission granted not by the local authority but by Parliament. Bear in mind that the permitted development rights which apply to many common projects for houses do not apply to flats, maisonettes or other buildings.
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.
There are also different requirements if the property is a listed building.
From 1 October 2008 an extension or addition to your home will be considered to be permitted
development, not requiring an application for planning permission, subject to the following limits and conditions:
- 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 meters for an attached house and four meters for a detached house.
- Maximum height of a single-storey rear extension of four meters.
- Maximum depth of a rear extension of more than one storey of three meters including ground floor.
- Maximum eaves height of an extension within two meters of the boundary of three meters.
- Maximum eaves and ridge height of extension no higher than existing house.
- Side extensions to be single storey with maximum height of four meters and width no more than half that of the original house.
- Two-storey extensions no closer than seven meters to rear boundary.
- Roof pitch of extensions higher than one storey to match 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.
