What happens while it is decided
The process from here
This application is with Camden for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
About reserved matters applications
How this application type works
A reserved matters application fills in the detail held back from an earlier outline permission, typically appearance, landscaping, layout, scale or access. The council judges it against the outline permission already granted, not the principle of development, which is settled. It must normally be submitted within three years of the outline decision.
