Conservatory planning permission

Do I Need Planning Permission to Build a Conservatory? 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: 1> No more than half the area of land around the "original house" would be covered by additions or other buildings. 2> No extension forward of the principal elevation or side elevation fronting a highway. 3> No extension to be higher than the highest part of the roof. 4> Maximum depth of a single-storey rear extension of three metres for an attached house and four metres for a detached house. 5> Maximum height of a single-storey rear extension of four metres. 6> Maximum depth of a rear extension of more than one storey of three metres including ground floor. 7> Maximum eaves height of an extension within two metres of the boundary of three metres. 8> Maximum eaves and ridge height of extension no higher than existing house. 9> Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house. 10> Roof pitch of extensions higher than one storey to match existing house. 11> No verandas, balconies or raised platforms. 12> On designated land no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions. 13> 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.
