• REAR OF 6 THE KEEP, BLACKHEATH, LONDON, SE3 0AF

  26/0507/TC Submitted 16 Feb 2026 0m away

  T1 Holm Oak - this tree, growing in the border of Morden Road Mews (to the rear of no.6 The Keep), requires pruning to manage its size for the residents of the garden over which it grows. It has been pruned on the road side, to allow bin lorries etc to pass freely, but has been allowed to overextend the garden quite considerably. As well as lifting the canopy by removing the lowest few branches over the boundary fence (to enable the owners to replace / repair structures in the back of the garden), we're applying to reduce the radial spread over the garden (of no.6 The Keep) by 2m from 5m to 3m to match the roadside and a reduction in height by 3m from 7m to 4m and shape accordingly.

  T1 Silver birch - fell to ground level and grind out root plate - less than six feet away from the front of the owners' property and double the height, several small cavities around the base of the primary stem, large number of cankerous growths all over the tree at every branch union and even along the secondary and tertiary stems in significant numbers right throughout the canopy - the tree has gone from shedding small wispy growth to losing larger stems from all over the canopy. clearly in decline and, given that silver birches are pioneer species and not long-lived. A replacement will be planted within roughly the same location.

  Elm (part of H1 on Survey) - fell. Reasons - growing in a raised border behind a retaining wall. It has been allowed to outgrow the hedge within which it sits and is now physically pushing against the wall. It will cause damage to the wall, which separates The Keep from the railway line, if left to its own devices. Arbutus (T001 on Survey) - Thin internal growth and remove crossing branches. Cut back from street light to give 1m clearance. Soft Maple (T9 on Survey) - Reduce to old points. Reduce height by 4m from 12m to 8m and radial spread by 3m from 6m to 3m all round.

  T4 Walnut - fell to ground level. As can be clearly seen from one of the photos, the surface dwelling roots of the Juglans are lifting the footpath and have become a trip hazard. Until now, the residents were happy to keep the tree as it adds to the streetscene in the locality. However, Openreach are now installing fibre optic broadband across the entire Cator Estate and the path under which the roots reside is going to be dug up to accommodate this upgrade. Thus, as noted in the Tree Survey, the tree needs to be removed as it would be unsafe to retain given the extensive root pruning that is required.
