Extensions, What Can I Do?

On 30th May 2014, a number of measures came in granting new permitted development rights in England. Now, an extension or addition to your house is considered to be permitted development and therefore not requiring a planning permission application, if the following limits and conditions are met.

Single Storey

Single storey extensions have to be less than 4m in height to the ridge and the eaves, and the ridge heights of any extension no larger than the existing property.

Single storey rear extensions must not extend beyond the rear of the original house by more than 6m for an attached house or by 4m for a detached house.

Two Storey

Two storey extensions must not be closer than 7m to the rear boundary.

They must not extend beyond the rear wall of the original house* by more than 3 metres.

Roof pitch of extensions higher than one storey must match existing house.

Side Extension

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

In Designated Areas** side extensions require planning permission and all rear extensions must also be single storey.

And Remember...

Extensions must not go beyond the building line of the original house.

An extension must not result in more than half the garden being covered. This includes previous extensions and sheds.

No extension to be higher than the highest part of the roof.

Extensions must be built in the same or similar material to the existing dwelling.

*The term 'original house' means the house as it was first built or as it stood in 1 July 1948.

**Designated land includes national parks and the Broads, Areas of Outstanding Beauty, conservation areas and World Heritage Sites.
