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 full applications applications
How this application type works
A full application seeks permission for a complete, detailed proposal in one go: siting, design, access and landscaping are all fixed at this stage. It is the standard route for new buildings, conversions and changes of use. The statutory target is eight weeks for smaller schemes and thirteen weeks for major development, though complex cases often take longer by agreement.

35 Hamilton Gardens London NW8 9PX
Lime tree in the front garden: Rempve epicormic growth to crown break at about 5m, and remove lateral epicormic growth growing over the front garden from the stem closest to the building of No.35; retaining shortened (about 0.5m long) vertical epicormic growth at the top of the stem, and retaining epicormic growth (on the same stem) that is growing towards the centre of the tree. the reason we need the work done is to observe the Jewish festival Sukkot when we build a temporary hut for the duration of the festival and reside in it. It is a requirement that the sky should be visible through the roof of the hut, hence the need to prune the tree.
