What happens while it is decided
The process from here
This application is with Westminster 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 conditions applications
How this application type works
This type of application deals with conditions attached to an existing permission, either by supplying the details a condition requires, called discharging it, or by asking to vary or remove one. It does not reopen the principle of the permission itself. Building often cannot lawfully start, or continue past a set stage, until the named conditions are discharged.
