Work you can do without planning permission (permitted development rights)
You may be able to do some building projects without planning permission. This is known as permitted development rights.
As the local planning authority, we can remove permitted development rights. You’ll need to find out if this has happened before you start your work.
If you’re doing your own research, you’ll need to check the full planning history of the property or land. You can do this by looking at planning permission decisions. They will contain conditions that have removed any development rights.
Works in a conservation area or on a listed building
If your property or land is in a conservation area, or if your building is listed, different planning rules may apply. Properties within an article 4 area have extra restrictions.
