Concept Planning can provide clear guidance as to what permitted development rights and identify pitfalls that often occur in areas that have additional restrictions. Certain types of extensions and development uses often do not require planning permission as they qualify under criteria know as Permitted Development.

Permitted development rights apply to both residential and non-residential properties and sites.
Securing the legality of both existing and proposed uses via certification by the local planning authority is often a straightforward method of achieving certainty of development and allowing piece of mind. The issuing of a Certificate of Lawfulness application is outside of planning policy and instead applies the General Permitted Development Order and case law judgements.
