Permitted Development

Certain types of operation are specifically excluded from the definition of development. Specified categories of minor, insignificant or allowed development are granted an automatic planning permission by law, and therefore do not require any application for planning permission. These categories are referred to as Permitted Development. Permitted Development covers many areas including minor development works, changes of use etc.
