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.

Tree applications cover work to protected trees: those under a tree preservation order need consent for pruning or felling, and trees in a conservation area need six weeks written notice before work starts. The council assesses the amenity value of the tree and can refuse consent, approve it with conditions, or in conservation areas make a preservation order in response.

  Flat A, 16 Mount View Road, Hornsey, London, N4 4HX

  There is a tree in the back garden I believe it’s a type of maple T1 , but not 100%. Its overdue a reduction. I've suggested around 2m off the top and match the sides to create a compound shape. It’s blocking out a lot of light to the end of the garden and is quite close to the buildings at the back.
