Development can have a significant impact on a neighbourhood and the environment.
Submitting a planning application gives an opportunity for the proposed development to be considered in its local setting. However, considering applications for minor and uncontroversial developments is not an efficient way of regulating development.
Permitted development rights are granted so that many instances of small alterations and extensions can be carried out without the need to submit an application for planning permission.
The purpose of the guidance is to explain the permitted development rights available to householders and therefore what can be built without submitting a planning application.
