What happens while it is decided

The process from here

This application is with Old Oak and Park Royal Development Corporation 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 outline applications

How this application type works

An outline application tests the principle of developing a site before the detail is worked up. Some or all of the particulars, such as appearance, layout, scale, access and landscaping, are held back as reserved matters for later approval. Permission at outline stage does not by itself allow building to start; the reserved matters must be approved first.
