Awaiting decision

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.

We planted an olive tree in the bed on the patio behind our house in 2004. It has apparently found a water source and grown much larger than originally expected. We have pruned it regularly, but it has continued to grow and is now disproportionately large for a relatively small patio area. Unfortunately, it has attracted a fungus, which produces substantial amounts of white residue and sticky deposits, which render the use of our outside space effectively impossible. We have taken advice from a tree surgeon, who has told us that without knowing the source of the infection (probably another fruit tree) it will not be feasible to eliminate this. The tree is also now too big to treat. In the light of this, we are seeking permission to cut the tree down.
