   Decision issued: Permitted Development

3. 24 Jul 2026

   Added to PlanIndex

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.

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

  This application is being filed for the consent to remove the robust Bay Tree (marked '1. Bay Tree' on the '8 Oldfield Mews Tree location.jpg') in the front garden of 8 Oldfield Mews, directly adjacent to the external wall of the property. We have attached the title plan with the approximate location of the tree marked. The tree has reached height over two and half storeys and has caused concern to the building structure, as outlined below: 1. Photographic evidence shows substantial ivy and woody vegetative growth to the masonry planter that abuts the front elevation of the property. 2. Damp has been reported by the tenant to a number of locations at the external wall adjacent to the tree. This issue has been present for the last 3 years, with past remedial works providing only temporary mitigation of the issue. Evidence of water ingress and staining is present to the internal linings to the front elevation. The vegetative growth is likely a contributing factor, with root structures causing damage to mortar joints and holding moisture against the external wall, and as further damp remedial work and internal redecoration are planned, felling the tree alongside these works would be advisable. 3. In addition to the damp, vegetation proximity to the property structures is a concern, with roots already causing visible cracking and bulging to the retaining planter wall so that further deterioration could lead to failure. The uPVC downpipe and guttering have also been displaced by stem growth. The extensive root systems could also lead to settlement and put further pressure on foundations. As far as we know, the tree isn’t protected by a TPO, and therefore we are requesting for its full removal by tree surgeon, due to its potential to compromise the structural integrity of the property's foundations and mitigate the damp issues at the ground floor level.
