  5 Highfield Road Southampton SO17 1NX

  T1 - Conifer (Unsure of species, possibly Leylandii or Cedar) on eastern boundary in rear garden. Remove tree with a view to planting a smaller, broadleaved alternative in its place. Resident is in the process of selling the property and has had consistent feedback that potential buyers are being put off by the how much light the tree takes up in the garden and through the rear windows. Tree was originally planted by resident's father. T2 - Leylandii Hedge on northern boundary in front driveway. Remove tall growth bringing height down by 4-5m down into the managed part of hedgerow below. Lower portion has been historically managed by the resident but the tall growth off of the back of the hedge has not been able to be managed and has grown too tall, interfering with guttering and blocking light to the windows at the front of the house.
