Decision & conditions

Refused Permission
Decision
Planning conditions
  1. In accordance with paragraphs 38-42 of the National Planning Policy Framework, Richmond upon Thames Borough Council takes a positive and proactive approach to the delivery of sustainable development, by: {\b o} Providing a formal pre-application service {\b o} Providing written policies and guidance, all of which is available to view on the Council's website {\b o} Where appropriate, negotiating amendments to secure a positive decision {\b o} Determining applications in a timely manner. In this instance: {\b o} The applicants did not seek formal pre-application advice, and the scheme was found to be contrary to policy and guidance, and subsequently refused. The Council is ready to enter into discussions, through the Council's formal pre-application service, to advise the applicants of relevant policy and guidance; and where possible assist in the preparation of a new planning permission. More information on the pre-application service and relevant fees can be found online at www.richmond.gov.uk/pre-application_for_developers.
  2. For the avoidance of doubt the Drawing(s) No(s) to which this decision refers are as follows:- 001; 002; 003; 004; 005; 006; 007; 008; 100; 101D; 102E; 103C; 104B; 105A; 106A; Tree Constraints Plan; Location Plan; and Application Form, received 12th June 2026.
  3. The proposed first floor extension, roof extensions, porch addition, fenestration and materials, by reason of their combined siting, depth, design and bulk, would result in an unsympathetic and incongruous form of development that causes 'less than substantial harm' to the character and appearance of the surrounding conservation area (designated heritage asset) without public benefits that significantly outweigh the harm and harm to the setting of the neighbouring Building of Townscape Merit (non-designated heritage asset). The scheme is therefore contrary to, in particular, policies 28, 29 & 30 of the Local Plan (2025), Supplementary Planning Document 'House Extensions and External Alterations' (2015) as supported by the St Margarets Conservation Area (CA19) Statement.
  4. The development, by reason of the absence of an Arboricultural Impact Assessment, Tree Protection Plan (TPP) and Arboricultural Method Statement has failed to demonstrate that the proposal would not detrimentally impact on the health and longevity of nearby trees to the detriment of the visual amenity of the locality and the character and appearance of the area. The proposal is contrary to the NPPF and, in particular, policies 28 and 42 of the Local Plan.
  5. In the absence of a Preliminary Ecological Appraisal and Bat Roost Assessment, the scheme fails to demonstrate that habiats and species will not be adversely impacted, and thereby fails to comply with the aims and objectives of the NPPF and Development Plan policies, in particular, part IV of Circular 06/2005 and Local Plan policy 39.
