You apply to your council for planning permission. Planning applications are decided in line with the development plan unless there are very good reasons not to do so. Points that will be looked at include the following:
- number, size, layout, siting and external appearance of buildings;
- proposed means of access, landscaping and impact on the neighbourhood;
- availability of infrastructure, such as roads and water supply; and
- proposed use of the development.
It is not necessary to make the application yourself. If you wish, you can appoint an agent (for instance, an architect, a solicitor, or a builder) to make it for you.
Anyone can make an application, irrespective of who owns the land or buildings concerned. However, if you are not the owner, or if you have only part-ownership, you have to inform the owner or those who share ownership, including any leaseholder whose lease still has seven or more years to run, and any agricultural tenant.
