What a grant of permission means

The process from here

Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.

Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.

About householder applications

How this application type works

Householder applications cover work to an existing house and its garden: extensions, loft and garage conversions, porches, outbuildings and similar alterations within the boundary of the home. They cannot be used to create a separate dwelling or change what the building is used for. Councils aim to decide them within eight weeks, and immediate neighbours are usually notified and given a chance to comment.

    4 ST MARGARET'S ROAD, LONDON, SE4 1YU

    REAR: ONE Lombardy Poplar (T1)(ht.17m) CROWN REDUCE HEIGHT by 5m from 17m to 12m, spread by 2m from 6m to 4m, CROWN THIN by 25 % Reason: reduction on all laterals and verticals, back to appropriate growth points, previously reduced, part of regular maintenance. REAR: ONE Lombardy Poplar (T2)(ht.10m) FELL. Reason: permission to fell was granted in 2017 (DC/17/104017) due to large basal decay cavity but works not carried out. Replanting proposed with an Acer within the rear garden. Informative A: the replacement tree is greatly appreciated, suggest such as Paperbark maple (Acer griseum), rather than Acer japonica which is prone to leaf scorch, other suitable species are such as: crab apple, hawthorn, Laburnum, pear (Pyrus communis), quince (Cydonia oblonga), hazel, Amelanchier, Magnolia Kobus, elder. Informative B: huge thank you for retaining T1 for amenity, wildlife, to reduce air pollution and to provide shade to reduce increasingly high summer temperatures due to climate change. Informative C: please leave a safe standing trunk of T2 and create habitat log piles with some arisings for wildlife and biodiversity. Informative D: The Bat Conservation Trust advises checking thoroughly for roosting bats before and during tree works with soft fell process followed to proceed with care and with cut timber left grounded over night to allow any bats to make their way out, tree works ideally during Sept/Oct to avoid maternity and hibernation seasons when bats are most vulnerable to disturbance.

    REAR: FIVE dead Leyland Cypress (T1-T5)(ht.3m) FELL. Duty to replace applies with species to be agreed with council - see Informative B below. Reason: dead monoliths, trees were cut down without permission by someone else some years back and are now decaying monoliths. Informative A: Duty to replace - the landowner has a duty to plant another tree of an appropriate size and species when a tree is removed in a conservation area because it is dead or presents an immediate risk of serious harm. Ref. Tree Preservation Orders and trees in conservation areas, guidance, para 121. Informative B: Replacement planting - 3 trees selected from: crab apple, quince, medlar, mulberry, pear, hazel, hawthorn to replace amenity, wildlife habitat and shade to reduce increasingly high summer temperatures due to climate change. Informative C: please create habitat log piles with some arisings for wildlife and biodiversity.
