17 South View Road, Hornsey, London, N8 7LU
Overview: Trees 3 (unknown) and 4 (Elder) have been smothered by ivy, compromising their health and structural integrity, and we would like to remove them so they do not pose a safety risk. Tree 2 (Elder) has similarly been strangled by ivy and is dying; we would like to remove it both on safety grounds and, as we have young children, to make full and safe use of the rear garden. Tree 1 (Talipot Palm) is not in keeping with the character of the conservation area, and we would like to replace it with a pear tree, a traditional fruit tree well suited to the cottage-garden character of the estate. Tree 5 (Elder), at the front of the property, is beginning to encroach onto the neighbouring property and we would like to remove.
