What happens while it is decided

The process from here

This application is with Islington 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 lawful development applications

How this application type works

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

    Erection of single storey side/ rear infill extension.

  • P2026/0380/TRE Granted

    Ground Floor Flat, 46 St George's Avenue, London, N7 0HD

    Rear garden- Honey Bean Locust (T1): Situated 2.7metres from property, planted close to the boundary with number 48 St.Georges Avenue. Crown reduction of this tree to 4 metres , to enable tree to be maintained upto 5 metres maximum height in future due to close proximity of tree to my property, with purpose of reducing potential for damage to property above ground from branches, and from root damage below ground to my property. Similarly to minimise risk of larger branches overhanging and impacting on the neighbouring property (number 48). I am aware this tree has a large ultimate height potential and I wish to make provision now to enable a straightforward maintenance plan for the future by reducing the crown ahead of this coming season of growth. My rear garden has many other mature trees situated further from the property that I do not wish to reduce in size or scale, I would like to make the point that I try to maintain my rear garden with a high visual amenity value overall for the area together with a wide diversity of mature tree species (in comparison with many surrounding gardens). However this single tree in my rear garden concerned with this application is very close to my property and my reasoning therefore is that I wish to take action towards minimising potential risk of damage to property. Front garden- Leylandi conifer (T2): Situated approximately 2metres from property, planted close to the boundary with number 48 St.Georges Avenue. Crown reduction- Leylandi to be pruned to 2metres height, to enable easier ongoing future maintenance thereafter at this height as a bush/hedge. Cordyline Australis (T3): Crown reduction in terms of height - pruned to 4.5 metres height.
