Permitted development rights are a type of general planning permission granted by Parliament. If your plans fall within certain restrictions, this allows you to bypass submitting a planning application.
Permitted development only applies to houses and outhouses (never flats or maisonettes), and there may also be exceptions if you live in a listed building or in a conservation area (‘Article 4’ direction). If you’ve had building work done in the past, you may also have used up your some or all of your permitted development rights.
Like planning permission, permitted development is regulated through your local planning authority. You should always speak to a qualified architect or designer to make sure your plans are compliant before you start building, and consider applying for a lawful development certificate.
If the legislation for permitted development on your project aren’t clear cut, or it has been conditionally withdrawn in your area, you should definitely apply for a lawful development certificate or may even need to submit a planning application.
However, we recommend it for everyone using their permitted development rights. The process ensures that your building work (past, present or future) is compliant, and will protect you when you come to sell your property.
The application process is similar to a planning application. You’ll need to provide:
Evidence verifying the information within the application.
This would include architectural plans and elevations
A site location plan

You’re usually within permitted development rights if your single storey extension or conservatory...
Sits to the side (as long as this will not face a highway) or rear of the house (not the front)
Must not extend beyond the rear wall of the existing house by 3m if an attached house or 4m if detached
Uses similar building materials to the existing house
Takes up less than 50% of the size of the land around the original house ("original" being the latest of when the property was built or if it was built before 1948, then as it stood on 1st July 1948)
If a side extension, is less than 50% of the width of the original house
Is less than 4m in height (or less than 3m if within 2m of a property boundary)
Has eaves and a ridge that are no taller than the existing house
These are just a few guidelines. There may be more criteria which you need to meet but we can cover that for you with our free phone consultations.

The following projects never fall within permitted development rights:
Whatever you’re hoping to build, your architect is likely to be able to make a few small changes that shift your plans within permitted development rights.
Even though you can build without applying for a lawful development certificate, it can be extremely risky. On the off-chance that your plans aren’t actually compliant with permitted development, you may have to remove your extension at your own expense or proceed with a lengthy and expensive legal battle over who is to blame.
