Please use the buttons to the side in the first instance to address any query on the need for planning permission. If you still require help you may want to consider seeking professional advice from a planning consultant or architect.
If you consider your proposal is permitted development and require written confirmation from the council that this is the case, you can submit an application for a Lawful Development Certificate for proposed development.
The application would need to be submitted on the planning application form and submitted with a location plan outlining the site in red, the relevant fee and plans of the proposal. A lawful development certificate can also be obtained for existing development.
