If you’re looking to add a conservatory to your home, you may not need planning permission. Conservatories are usually exempt from building regulations when:
The main thing you need to consider is the size of the conservatory in relation to your home. The Government’s conditions state that no more than half of the area of land around the original house can be covered by additions or other buildings, including conservatories. The ‘original house’ is the house as it was first built, or as it stood on 1st July 1948 if it was built prior to that date.
Previously the limit on the size of a conservatory was 4m from the rear wall of your home for a detached house, and 3m for all other house types. However, this was changed due to new guidance called the Neighbour Consultation Scheme which started 30th May 2013 and is running until 30th May 2019. This guidance increased the size of conservatory extensions, doubling the limit to 8m for a detached property and 6m for other property types.
If you plan on adding a conservatory under these new guidelines, you’ll need to follow a slightly different process, full details of which can be viewed here.
Once you’ve notified your local planning authority, they will contact your neighbours who 21 days to object.
In addition to the position of your new conservatory, you also need to consider conditions relating to the structural elements. Full details can be viewed here.
If your property is in a conservation area or an area of outstanding natural beauty, there may not be any permitted development for a side extension, a rear extension of more than one storey high or external cladding so you need to check the rights of the property more closely.
If your conservatory doesn’t meet the Government’s conditions then you’ll need to submit a planning application in the normal way to your Local Building Authority. This costs around £150 in England and can take up to eight weeks to process.
