This application is at appeal, which passes the decision from Camden to the planning inspectorate, and the outcome will replace the council's decision. More in our guide to what happens after a planning decision.

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.
