Haringey refused this application for the reasons on the decision notice; only the applicant can appeal, and refused schemes often return in revised form. More in our guide to what happens after a planning decision.

An amendment application makes limited changes to a permission that already exists; anything beyond modest adjustment needs a fresh application. More in our guide to planning application types.

  Proposal: We are proposing to have the large lime tree at the bottom of our garden pruned professionally, as part of the cycle of regular pruning. The proposed work is a 30% crown reduction and thinning back to previous reduction points. I would estimate that the tree is about 15 metres high, so we are requesting a reduction of some 4-5 metres. The tree was last pruned in 2021 under your reference CON/2021/0518: it is in a Conservation Area, but not subject to a Tree Preservation Order.
