    TPO564 Sandy Lane, Northwood. Species/Description: Conifer (TPO tree. Ref T108). We have a large conifer in our garden (see sketch plan where the conifer is highlighted yellow). It is c. 15 metres high with wide branches. It is has grown to the extent that the area of garden around it is now in the shade and other plants/grass cannot grown because the sunlight is blocked out. We intend to trim/prune the conifer (using professional tree surgeons) to reduce the size by c. 33%.
