The permitted development rules have changed recently, allowing more freedom for householders. Information on permitted development rights can be found here.
However, the complexity of the wording of the rules has meant that there are inconsistencies in the way Local Planning Authorities interpret them. Therefore, it is almost essential to apply for a Certificate of Lawfulness before commencing any building work.
c2c Planning Consultants can assist you with your Certificate of Lawfulness application to ensure your proposed development complies with the rules.
