Eton Court, 6 Shepherds Hill, Hornsey, London, N6 5AF

Works to tree protected by a TPO. Sycamore - Crown reduce the height and spread 0.8m-1.0m past the previous reduction points (approx. 40%) height approx. 3.5m and spread approx. 3.0m Remove dead wood The tree is situated on unregistered/ownerless land adjacent to our residential block and is causing ongoing damage to essential drainage infrastructure. The root system has infiltrated the sewage pit serving the building and is interfering with the float mechanism of the sewage lifting pump. This has already resulted in operational issues, including the pump cutting out. In February 2026, a contractor removed a significant quantity of roots from the chamber and advised that further root ingress is likely due to the proximity and size of the tree. Continued root growth presents a risk of pump failure and potential sewage backflow, with associated health and property damage implications. The proposed 40% crown reduction is intended as a proportionate management measure to reduce the tree’s water demand and vigour, thereby helping to limit further root encroachment, while retaining the tree and its amenity value.

6 Acorn Terrace, Archway Road, Hornsey, London, N6 4BF

T1 mature Sycamore tree in the back garden. The total height of the tree is ~25 metres. As you can see from the side view photo, it sits between the buildings and the Highgate wood trees on the right. A wind tunnel effect is created between the buildings and the woods and, when full of leaf, our tree acts as a sail. There is a risk that it may be uprooted in strong windy weather. The proposal is to reduce the volume of the crown, so in practical terms this would be to reduce the height by around 2-3 metres but then to thin out the bulk of the branches, taking some back by half their length whilst leaving others intact. This would limit the impact of the wind and preserve the tree. An arborist will assess which particular branches will be shortened whilst he is working on the tree.
