Replacement of existing timber windows with double glazed timber windows
51 Cromwell Avenue Hornsey London N6 5HP · premises record

Approved

T1 Lime tree Crown thin 30%, remove deadwood The tree is 25m high and the centre of the canopy is very congested. Thinning would improve light to the surrounding gardens and the removal of dead growth (incuding some very substantial dead limbs) would be in the tree's interest as well as the welfare of those using the gardens beneath.
