Before you start any building work or make any changes to your property you must check if you need planning permission.
Your project can be affected by two types of constraints. These are:
- national guidance on what is allowed, known as permitted development rights
- local constraints, including whether your property is in an area that we have restricted development on
Flats and maisonettes don't have any permitted development rights, so if you plan to change the outside appearance of a flat you'll need planning permission.
