  • Maximum height of 2.5 metres in the case of a building,
  • No more than half the area of land around the "original house"* would be covered by additions or other buildings.

*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.
