This application is with Camden for determination, against a statutory target of eight weeks. Over the last year Camden's median decision took 43 days. More in our guide to how long planning decisions take.

A reserved matters application fills in the detail held back from an earlier outline permission, judged against that permission rather than the principle of development. More in our guide to planning application types.
