In the garden, we have a horse chestnut tree. The tree needs cutting back and branches cut as the overall size of the tree since we have moved in has grown considerably. It is now spanning multiple gardens and has caused damage to next door as, when they were away, bird droppings from birds in the tree caused the fish in their pond to all die. Since then, they have had to get rid of the pond. We are wanting the overall size of the branches to be cut back considerably. If possible, so that the branches only span our garden. The number of the sketch plan is T17.
