Haringey granted permission on 3 September 2021, subject to any conditions on the decision notice. Work must normally begin within three years or the permission lapses. 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.

  T01: Multi-stemmed Ash (Fraxinus excelsior) located within the rear garden of the property. Crown reduce the overall height and lateral canopy spread of T01 (Ash) by 30% (equivalent to a radial branch reduction of 3.0 to 4.0 metres), pruning back to suitable, established previous reduction points. Note: All pruning works are to be carried out in strict accordance with British Standard 3998:2010 (Recommendations for Tree Work). The subject tree is a mature, multi-stemmed specimen that has regrown from a historic stump to form 5 large codominant stems. The primary union at 0.5 metres is heavily included and represents a potential structural weakness. Visible expansion cracks on the primary stems and secondary branches indicate rapid adaptive growth in response to physical stress and wind-loading. The proposed 30% (3–4m) crown reduction is specified to reduce the "wind sail" area and mechanical loading on this included primary union, managing the structural risk of stem failure. Additionally, the reduction will abate lateral encroachment and foreseeable future nuisance to neighbouring properties.
