Can I build a conservatory without planning permission?

The honest answer is that it depends on the size of the extension and the location of the conservatory. In many cases, you will not require planning permission to install a conservatory. It will be deemed by your local authority as permitted development. Without getting too technical, to avoid planning permission, the most important criteria to be aware of is:

  • No more than half the land area around the original house can be covered by the conservatory
  • The conservatory must not extend over four metres and up to 8 metres from the back of the property (detached houses) or over three metres and up to 6 metres (any other houses)
  • The conservatory’s height must not exceed that of the original property and be no more than four metres in height.

If you live in a conservation area or a listed building, other limitations may also apply. But for many homeowners, these criteria will not pose a problem for most conservatory installation plans. The Oakley Green team expertly overcome most obstacles surrounding planning permission and can offer professional advice on the best solution for your conservatory installation plans.

Can I build a side extension without planning permission?

For most homeowners, extending from the rear of your property is usually the preferred option. For some people, however, it will make more sense to build a side extension. Side extensions face stricter regulations than rear extensions. Other than the points listed above, according to the government’s Planning Portal, for a side extension to be considered permitted development and not need planning permission acceptance, it must:

  • Not extend from the front of the building or the side of the building (if the side elevation faces the main road)
  • Not exceed four metres in height and not exceed more than half the width of the original property (side extensions).

If you’re planning a side extension, you may need to refer to the Neighbour Consultation Scheme depending on the impact your extension may have on their home life.
