                      Further advice

                      We strongly advise that in the event that an extension you are proposing does fall within one of the above classes of development and does not require planning permission that you apply for a Certificate of Lawfulness for the proposal. This is a legal determination as to the need for planning permission for a proposed extension.

                      Please contact us for further information. We would be pleased to explain.

                      The interaction between the classes can be complex. If you are considering an extension to your building which would involve more than one of the above classes of development or more than one element of one of the classes, and planning permission would be required for only part of the overall proposal, please contact us.
