Tree Removal Section 211 Notification – Islington Conservation Area Site Address: 27 Highbury Hill Tree Details: Tree 1 Species: Crabapple tree Location: Rear garden, close to boundary party wall Proposed Work: Removal Tree 2 Species: Japanese Maple tree Location: Rear garden, close to boundary party wall Proposed Work: Removal Reason for Proposed Work The two trees are located within the rear garden of the property, in close proximity to the boundary party walls. Construction works are currently being carried out nearby, as part of a previously approved rear extension and basement excavation. The newly approved structure is positioned on top of or very close to the current location of both trees. Given their proximity to the construction area, retaining or relocating the trees poses a high risk to their long-term health, particularly due to potential damage to their root systems. For this reason, we are proposing their removal. We intend to replace the trees with new ones following completion of the building works. The replacement trees will be planted in more suitable locations within the garden, and low-level vegetation will also be introduced to enhance the landscaping.
