Crown lift of tulip tree (rear garden) - branches overhanging boundary wall with Bath Place risking damage to wall and loss of light to garden. Crown lift of ash tree (rear garden) - branches overhanging neighbour's property risking damage to fence and cutting out light (14 Chilbolton Avenue) I believe 5-5.5m from ground level on our side would suffice for the tulip and ash tree. Remove hazel from 14 Chilbolton Avenue (front garden) as branches are causing damage to flat roof causing a nuisance (neighbours have agreed to this work)
