Planning application

9 Southwood Mansions, Southwood Lane, Hornsey, London, N6 5SZ

Decided Haringey HGY/2026/2180 Works to trees in Conservation Area

Works: Trees

Decided. The decision notice on the council portal carries the outcome in full, including any conditions.

Proposal

Front garden: fig (T1) - fell. Reason: An initial assessment (not a full arboricultual survey) indicates the tree is the likely cause of cracking in the pavement. The roots will continue to expand and so cracking will likely continue to worsen. Pruning will not significantly reduce damage over the medium term. The cracking can be seen extending towards the building. The tree is located around 2m from the building. British Geology Survey maps show the property sited on Claygate member clay which is not as shrinkable as London clay but is still considered to have medium to high shrinkability. This could be confirmed through lab soil tests. Considering the period of the building, the foundations are likely to be shallow strip foundations. This could be confirmed through exploratory digging.

    Dawn Redwood. Tree T1 on Sketch Plan. Arboriculturist Conclusion "Given the presence of cracks in the wall of adjacent buildings, and the close proximity of the tree to the buildings, it is recommended that T1 is removed to ground level." Engineer's Conclusion "the best course of action to avoid any further movement on the existing building would be to remove the existing tree and underpin the existing foundation"

    Pembury House Nursery, Lansdowne Road, Tottenham, London, N17 9XE

    Ginkgo (T1) - fell. Reason: this is a female tree, that drops fruit all over the nursery playground. The children try to eat them, it gets into their clothes, shoes, hands, and all over the class room, creating an extremely unpleasant environment for the children and staff. Replant with another deciduous tree with similar potential size canopy (eg. Norway maple) Sycamore (T2) - Reduce the height of the tree by 4m. Reduce lateral branches in line with this (up to 2.5m). Reason: There is some decay at the base of the tree on the east side, spanning 40% of the circumference of the tree. The bark is flaking from ground level up to 1.5m, and use of the sounding mallet indicates the dysfunctional wood extends at least to the same height. The tree has a full crown, but has had selective branch length reductions in the past. The crown overhangs the nursery playground and neighbouring parking area. Lime x2 (T10 & T11) - Crown raise to 4m, removing epicormic growth. Reason: to remove the branches that touch the shelter to prevent damage.
