A Simple Guide to Planning Permission for Conservatories and OrangeriesPublished on 4th February 2016
Planning a new conservatory is an exciting time, but it’s easy to find it scuppered by planning permission in the later stages if you don’t do your homework first.
Under the regulations that came into effect on 1stOctober 2008, conservatories are considered to be permitted development, that means they don’t need planning permission. However this is subject to local planning permission and building rules, plus other regulations such as whether your house is listed and the area in which you live.
As with any permanent structure, there are limitations to permitted developments…
If your home is a standard construction build, not a listed property nor within the bounds of a national park or area of natural beauty, then planning permission for a conservatory should be a straight forward process. Furthermore, there are a number of rules that must be met in accordance with any such development, for example your conservatory cannot cover more than half of your garden and it must not be higher than the height of your existing roof.
Other conditions include: extensions that are more than one storey must not extend beyond the rear wall of the original house by more than three metres or be within seven metres of any boundary opposite the rear wall of the house. Side extensions must be single storey with a maximum height of four metres and width no more than half that of the original house. Also, permitted developments do not include verandas, balconies or raised platforms.
Homes within national park borders
Conservatories are also permitted developments for homes that are on “designated land” (this includes national parks, areas of outstanding natural beauty, conservation areas and World Heritage Sites) however the rules are a little more stringent.
You cannot build an extension of more than one storey on designated land, it must not be cladded and you are only allowed to build on the rear of the property, not the sides. Furthermore, the structure must not extend more than three metres from the wall of the original house if it is an attached house, or four metres for detached houses.
As with any redevelopment work on listed properties you may need listed building consent in order to build any sort of conservatory onto such a property. The factors vary widely depending on the reasons for the building being listed, the local significance of the building and which listed category it falls under.
Permission for larger conservatories
If you plan to build a substantial conservatory or something bigger than half of your garden, you will need to seek planning permission.
Orangery planning permission comes under the same rules as those for a standard conservatory.
Whatever your properties dynamics, it is always worth consulting with an expert supplier or someone reputably informed about building regulations.Failure to apply for permission when it is required could be a very expensive oversight in the long run.
