    T1. Sycamore (Acer psuedoplatanus) Rear garden Large mature tree dominating rear garden and overhanging adjacent gardens. Snapped branches throughout canopy, and squirrel damage on new growth. Previously reduced 4 years ago. Reduce canopy to previous points of reduction (3m in height and 2m in lateral spread) to maintain cyclical pruning and improve light into surrounding areas.

    Ash tree (self seeding) within 0.5m from boundary wall. Our property is located on shrinkable London clay soil. Fast-growing, high-water-demand trees situated within half a metre of building foundations present a long-term risk of soil desiccation, clay shrinkage, and potential foundation movement. We have been advised to remove the tree to ground level.
