Rules governing outbuildings apply to sheds, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structure for a purpose incidental to the enjoyment of the dwelling house.
Under new regulations The Town and Country Planning (General Permitted Development) (Amendment) (No. 2) (England) Order 2008 that came into effect on 1 October 2008 outbuildings are considered to be permitted development under Class E, not needing planning permission, subject to the following limits and conditions:
*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.
