• No more than half the area of land around the 'original house'* would to be covered by extensions or other out buildings.
• No conservatory forward of the principal elevation or side elevation fronting towards a highway, a highway would include public footpaths and roads
• A single storey rear conservatory must not extend beyond the rear wall of the 'original house'* by more than 3 metres (semi-detached / terrace house) and 4 metres for a detached house.
• The maximum height of the new conservatory to be 4 metres. This would mean any part of the conservatory including the ridge.
• No conservatory to be higher than the highest part of the original house roof.
• The maximum eaves height of a conservatory within 2 metres of the boundary of 3 metres high.
• The roof pitch of a conservatory higher than one storey to match the existing house.
• A new conservatory to be single storey with maximum height of 4 metres and width no more than half that of the original house.
• On certain designated land* no permitted development for rear conservatories of more than one storey; no cladding of the exterior; no side conservatories.

* 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.
