Planning Regulations...

The building of a new dwelling and extensive changes to existing buildings usually requires consent from the local planning authority in the form of planning permission. Adding outbuildings or building extensions will require planning permission, depending on the size of the project.

Smaller additions and improvements can normally be made under your Permitted Development Rights.


An addition or extension to your house is generally considered to be permitted developments. Planning permission is not required as long as:

• Your extension is no more than half the area of land around the original house (curtilage). The “original house” is seen as it was in 1948; after this date how it was newly built

• Your extension is not forward of the principal elevation or side elevation onto a highway

• Your extension is not higher than the highest part of the roof

• In the case of single storey extensions, it must not extend beyond the rear wall of the original house by more than three metres if an attached house or by four metres if a detached house

• The maximum height of your single-storey rear extension is not higher than four metres

• Extensions of more than one storey do not extend beyond the rear wall of the original house by more than three metres

• Side extensions are single storey with maximum height of four metres and width no more than half that of the original house

• Two-storey extensions are no closer than seven metres to rear boundary

• The materials are similar in appearance to the existing house

• Your extension does not include verandas, balconies or raised platforms

• Any upper-floor, side-facing windows are obscure-glazed; any opening is 1.7m above the floor Conservatories are categorized as the same as any other extension, as set out above.

There are also different planning restrictions for designated areas such as Conservation areas and if your property is listed.

Loft Conversions

Planning permission is not normally required, unless you are extending the roof space or exceed specified limits e.g. any dormer is higher than the current highest part of the roof or you live within a conservation area.

New Builds

Planning permission is required for all new builds. Consideration needs to be made for design, access, waste storage and collection and parking for the application to be successful

Garage Conversions

Planning permission is not usually required, providing the work is internal and does not involve enlarging the building. Sometimes permitted development rights have been removed from some properties with regard to garage conversions and therefore you should contact your local planning authority before proceeding, particularly if you live on a new housing development or in a conservation area.

Where work is proposed to a listed building, listed building consent may be required.
