43 Langdon Park Road, Hornsey, London, N6 5PT

Works to tree protected by a TPO. The tree in this case is a European Lime (tilia x europaea). T008 - Find on sketch plan. The works we are requesting for the lime tree is for it to be removed. In the report attached the lime tree is referenced as (T008). T008 is a European lime tree in close proximity to the property, at the front if the boundary wall of 43 Langdon Park Road. This application proposes the removal of the T008 to avoid current and future structural damage to the property, drainage and boundaries. Upon a professional observation of T008, the report advised that T008's size and close proximity to the building is causing damage and will likely lead to further structural issues particularly heave due to the age of the tree. T008 is placing undue stress on the buildings structure. Neighbours have informed that the main foul waste sewerage runs directly beneath the tree and that it becomes blocked by the trees roots. Even the team carrying out the tree investigation whilst on site experienced blockages which they had to address by rodding the drains themselves. They have also reported damage to infrastructure and damage to their property. Neighbours have reported damage caused by T008 and request it also be removed.
