Restrictions on permitted development rights (Article 3 restrictions)
Permitted development rights allow certain property owners to carry out improvement works and/or extensions, without the need for planning permiission - find out more.
For some developments such as barn conversions or areas such as conservation areas and new housing developments some developments that do not normally need planning permission may still need permission.
It is also possible that your property may have had its permitted development rights removed - so we would always encourage you to check first by doing a planning history search.
The government have published a guidance document on householder permitted development rights to help homeowners understand how they can use their permitted development rights to carry out extensions and improvements. It is designed to be used by anyone who wants to understand more about the detailed rules on householder permitted development and the terms used in those rules.
