Planning Permission









Planning Permission

Under new regulations that came into effect from 1 October 2008 adding a conservatory to your home is considered to be permitted development, not needing an application for planning permission, subject to the following limits and conditions:

- No 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 metres for an attached house and four metres for a detached house.
- Maximum height of a single-storey rear extension of four metres.
- Maximum depth of a rear extension of more than one storey of three metres including ground floor.
- Maximum eaves height of an extension within two metres of the boundary of three metres.
- Maximum eaves and ridge height of extension no higher than existing house.
- Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
- Roof pitch of extensions higher than one storey to match existing house.
- No verandas, balconies or raised platforms.
- On designated land* no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions.

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

* 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.

Ten tips to help your planning application succeed:

- Discuss your ideas informally first with the planning officer.
- Produce drawings/plans and photographs.
- Tell your neighbours so they won't object.
- Look for similar extensions in your area.
- If you live in a listed building discuss your proposal with the conservation officer first.
- Emphasise the build quality, produce examples of our projects; use precedent.
- Be prepared to compromise.
- Remember designs should be sympathetic and subordinate, not overpowering.
- Pick out features of the house and introduce them into your design.
- Avoid schemes that would dramatically change the historic fabric of your house
