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.
