What happens while it is decided

This application is with Islington for determination, against a statutory target of eight weeks. Over the last year Islington decided householder applications in a median of 56 days. More in our guide to how long planning decisions take.

About householder applications

Householder applications cover work to an existing house and its garden, such as extensions, lofts and outbuildings, and cannot create a separate dwelling or change what the building is used for. More in our guide to planning application types.

    This is a small (3m tall) Viburnum tree in a small north facing back garden, not visible from the road. There is another Viburnum, and a bay tree in the same garden. There are other, bigger trees in adjacent gardens. This tree blocks light, and passage to the garden. Propose to remove. Plan to replace with a smaller shrub. Not another tree, given the small garden size and the number of other trees nearby.
