What happens while it is decided
The process from here
This application is with Cambridge 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 prior approval applications
How this application type works
Prior approval applications arise where permitted development rights already grant the principle of the work, such as larger home extensions, changes of use to housing or agricultural buildings. The council may only consider the specific matters set out in the rules, for example transport, flooding or appearance, and in many classes the work may proceed if the council does not respond within the deadline, commonly 56 days.
