  100% historically approved · decision due ~18 May

  T1 & T2 – Lime (Tilia sp.) Crown reduction by approximately 20–25% to reduce height and lateral spread, selective crown thinning to improve light penetration, and removal of any dead, diseased or crossing branches. All works to be carried out in accordance with BS3998:2010. The proposed works are required to manage the size and spread of the trees, as the branches have become overextended within the garden setting. The works will help maintain a balanced crown, improve light to the garden, and ensure the trees remain suitable for their residential context. The proposals are minor in nature and will not adversely affect the health, appearance, or amenity value of the trees.
