This application is with Camden for determination, against a statutory target of eight weeks. Over the last year Camden decided heritage and listed building applications in a median of 55 days. More in our guide to how long planning decisions take.

Listed building consent is needed for works that affect the special interest of a listed building, and carrying out such works without it is a criminal offence. More in our guide to planning application types.
