Permitted Development Rights – Single Storey Extension

Homeowners can perform certain types of building work to their home without needing to apply for planning permission. These are called Permitted Development Rights. In some parts of the country, known generally as ‘designated areas’, permitted development rights are more restricted. In this instance you will need to apply for planning permission for certain types of work which do not need an application in other areas. For example if you live in:

  • A Conservation Area;
  • An Area of Outstanding Natural Beauty;
  • A National Park;
  • A World Heritage Site;
  • The Norfolk or Suffolk Broads,

Permitted Development Rights for Single Storey Extensions

The following conditions are to be met Under Permitted Development Rights for Single Storey Extensions:

Extensions (including previous extensions) and other buildings must not exceed 50% of the total area of land around the original house. The term ‘original house’ means the house as it was first built or as it stood on 1 July 1948. Although you may not have built an extension to the house, a previous owner may have done so. Sheds and other outbuildings must be included when calculating the 50% limit.

Extensions forward of the principal elevation or side elevation of a house and fronting a highway are not permitted development.

Materials used in exterior work to be similar in appearance to those of the exterior of the existing house.

Side extensions to be single storey with a maximum height of four metres.

If extension is within two metres of a boundary the maximum eaves height should be no higher than three metres.

Single storey rear extension must not extend beyond the rear of the original house by more than 3m for a terraced or semi-detached property or by 4m if a detached property. In addition to this condition, you can extend beyond the rear of the original house by 6m for a terraced or semi-detached property and 8m from a detached property under the neighbour consultation scheme.

Single storey rear extension must not exceed a height of four metres. Maximum eaves and ridge height of extension to be no higher than the existing house.
