The process from here
Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.
Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.
About amendments applications
How this application type works
An amendment application changes a permission that already exists. Non-material amendments cover small adjustments with no wider effect, while minor material amendments, usually made by varying a condition, allow modest design changes without a fresh application. Anything beyond that needs a new permission, so the scope here is deliberately narrow.

Works to a tree in a conservation area: T1. Pear Tree. In rear garden of 32 Freemantle Street. Proposed works: Removal by sectional felling. Reasons for desired works: The tree consumes most of the space in the small rear garden and is creating an excessively gloomy environment in the garden and back rooms of the flat. It is fairly tall for a pear tree and not appropriate for such a small garden.
