House extension permitted development rules

Will i need planning permission for my rear house extension?

 

Single-storey extension


An extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, provided certain limits and conditions are met. If you own a ground floor flat then planning permission would be required.
 

1. On designated land* - no cladding of the exterior. *Designated land (Article 2(3)) includes national parks
and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.
2. On designated land* - no side extensions. Rear extension - No permitted development for rear extensions of more than one storey. The regime for larger single-storey rear extensions
3. No more than half the area of land around the “original house”* would be covered by additions or
other buildings. Sheds and other outbuildings must be included when calculating the 50 per cent limit. 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.
4. No extension forward of the principal elevation or side elevation fronting a highway.
5. Materials to be similar in appearance to the existing house.
6. Side extensions to be single storey. Width of side extension must not have a width greater than half the width of the original house.
7. Side extensions to have a maximum height of four metres and width no more than half that of the original house.
8. If the extension is within 2m of a boundary, maximum eaves height should be no higher than 3m to be permitted development.

9. Single-storey rear extensions must not extend beyond the rear wall of the original house* by more than 4m if a detached house; or more than 3m for any other house.

10. Maximum height of a single-storey rear extension of 4m.

11. Maximum eaves and ridge height of extension no higher than existing house.

Will i need planning permission for my side return house extension?

 

A side return extension is considered to be permitted development (PD) — in other words, it doesn’t need planning permission as long as it satisfies certain criteria. First and foremost, it must be attached to a house (flats and maisonettes don’t qualify). Plus, PD rights may be restricted if your home is in a conservation area. Speak to your architect about this or consult your local council directly.

A side return extension must be single storey (no more than four metres high) and must not exceed more than half the area of land around the original house (as it was first built or as it stood on 1 July 1948 if it was built before that date). It must also be no wider than half the width of the original house. If the extension is within two metres of a boundary, maximum eaves height should be no higher than three metres to be permitted development.

As well as satisfying these conditions, you’ll need to notify the local authority of your proposal and formally consult neighbours. If there are objections, the proposal might not be allowed, so it’s wise to seek advice before getting started.
