With so many potential planning and building regulations relating to the erection of conservatories here in the UK, we thought you would find the following summary of benefit. This information only relates to England as the regulations differ in Wales, Scotland, Northern Ireland and Eire. We would recommend that you only use the under mentioned as a guide and that you obtain specific advice yourself.
On the 1st October 2008, there were changes made relating to planning permission for conservatories. For instance, the erection of a conservatory at your home would be classed as permitted development if the following conditions were applicable. If this were the case, planning permission is not required.
- A single storey rear extension with a maximum height of 4 metres.
- The height of an extension should not exceed the roof’s highest point.
- An extension to the side of the property should be single storey with the width not exceeding 50% of the original home and no more than 4 metres high.
- There should be no raised platforms, balconies or verandas.
- Other buildings or additions would cover in excess of 50% of the area of the land that surrounds the “original house” with the later meaning the house as it was originally constructed or as it was way back on the 1st July 1948 if it happened to have been erected prior to the aforementioned date. Whilst an extension might not have been constructed for you it may have been done for an earlier occupant.
- 3 metres is the maximum depth that also includes the ground floor, for a rear extension that exceeds one storey.
- A rear single storey extension should not exceed 4 metres in depth for a detached home and 3 metres for an attached home.
- With extensions of more than 1 storey the pitch of the roof should be the same as the existing home.
- If the extension is closer than 2 metres to the boundary the height of the eaves should not exceed 3 metres.
- When the property fronts a highway an extension must not be forward of a side or principal elevation.
- It may be necessary to obtain listed building consent if it is intended to carry out work to a listed building.
- The height of the ridge and eaves on an extension should not exceed the height of the existing home.
- On designated land i.e. conservation areas, the Norfolk Broads, World Heritage Sites, National Parks and Areas of Outstanding Natural Beauty no extensions to the side of the home are allowed, no exterior cladding can be done and no permitted development in respect of rear extensions that exceed 1 storey.
The above information is purely for your guidance and you should get in touch with the local authority dealing with building and planning regulations for specific guidance prior to work starting.
