Before asking for planning permission (which makes it public) you can complete a planning enquiry form. This is a good idea if you are unsure if planning is needed and indeed to get a feel for how well an application might be received. If you are sure that you do not require planning you can apply for a ‘Lawful Development Certificate’ which might be useful in later years if you ever sell your property as it would avoid any ambiguity about whether or not the property fell within planning restrictions at the time it was built. If in a rush, as Lucy was, you could just start the planning application process immediately. Forms needed to be completed and Lucy paid a refundable fee to Keops to produce scale drawings to support the application although you can produce your own. Lucy also purchased online maps that are necessary as part of the process to clearly and accurately outline the boundary of her property, current buildings and proposed build area.
