What happens while it is decided

This application is with Barnet for determination, against a statutory target of eight weeks. Over the last year Barnet decided householder applications in a median of 56 days. More in our guide to how long planning decisions take.

About householder applications

Householder applications cover work to an existing house and its garden, such as extensions, lofts and outbuildings, and cannot create a separate dwelling or change what the building is used for. More in our guide to planning application types.
