This application is with Cardiff for determination, against a statutory target of eight weeks. Over the last year Cardiff decided householder applications in a median of 62 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.
