In 2020 we applies dor 3 large Conifers at rear of property, close to back of the house. We cut down 2 and now wish to fell the third (T1). This is close to house, taller than house and restricts light into neighbours and our house. It has caused problems in neighbours drains and restricts growth of a Silver Birch. T2, Conifer is rear of garden and restricts any other plant growth. HAR/CA14.

Rear garden is 29m x 15m with many trees (see diagram). We wish to cut down the Leylandii which is growing up and through the Ash tree. In addition we wish to have a tree surgeon reduce the crown of the Ash by no more than 30%. The Leylandii is referenced tree 1 and the Ash tree 2. The Ash we believe was taken back via a similar crown reduction many years ago, but has grown a lot in this time. In addition the Leylandii has grown much more and as it is less than 2m away is completely overpowering the Ash tree, it is also now taller than the Ash. HAR/CA14
