  T1 - Holly tree - we would like to reduce the tree by about 2-3 metres back to previous points to maintain a balanced shape and bring more light in to the properties and gardens. T2 - Lime tree - we would like to reduce the tree more significantly than the trees have always be done. I have attached a photo indicating the level we would like to reduce it to. It would be reducing it by about 4-5 metres, to points which can maintain a balanced shape. The aim is to bring more light in to the gardens and all the neighbouring gardens as they restrict a lot of light. Maintaining a good shape would still be the main objective whilst bringing more light for all the neighbours.
