Decision & conditions

Refused Permission
decision
Planning conditions
  1. The proposed development, in the absence of sufficient arboricultural information by way of an Arboricultural Impact Assessment (AIA), Tree Protection Plan (TPP) and Arboricultural Method Statement (AMS), 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 therefore contrary to the NPPF and, in particular, policies 28 and 42 of the Local Plan.
  2. Due to the unsatisfactory refuse storage and disposal arrangements and absence of justification for such, the proposed development fails to comply with the NPPF, Local Plan policy 7 and Refuse and the Recycling Storage Requirements SPD.
  3. In the absence of a satisfactory completed energy statement and section 106 agreement securing an off-site zero-carbon contribution, the proposed development fails to demonstrate that it will achieve the highest standards of sustainable design and construction to mitigate the effects of climate change, or otherwise justify a lesser standard, and thereby fails to comply with the aims and objectives, in particular, policies 3, 4 and 6 of the Local Plan and Supplementary Planning Document 'Sustainable Construction Checklist'.
  4. 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: * Providing a formal pre-application service * Providing written policies and guidance, all of which is available to view on the Council's website * Where appropriate, negotiating amendments to secure a positive decision * Determining applications in a timely manner. In this instance: * The applicants did seek formal pre-application advice, however, the Council's recommendations for amendments were not followed, and the scheme was found to be contrary to policy and guidance, and therefore the application was 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.
  5. For the avoidance of doubt the Drawing(s) No(s) and Document(s) to which this decision refers are as follows:- - Existing Ground Floor Plan 0901-WPA-0010 REV P1 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing 1st and 2nd Floor Plan 0901-WPA-0011 REV P1 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing 3rd Floor Plan 0901-WPA-0012 REV P1 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing 4th Floor Plan 0901-WPA-0013 REV P1 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing East Elevation 0901-WPA-0020 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing South Elevation 0901-WPA-0021 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing West Elevation 0901-WPA-0022 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing North Elevation 0901-WPA-0023 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing Section AA 0901-WPA-0030 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Existing Section BB 0901-WPA-0031 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed Fourth Floor Plan 0901-WPA-0101 REV P1 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed Ground Floor Plan 0901-WPA-0110 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed Third Floor Plan 0901-WPA-0100 REV P1 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed East Elevation 0901-WPA-0200 P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed South Elevation 0901-WPA-0201 P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed West Elevation 0901-WPA-0202 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed North Elevation 0901-WPA-0203 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed Section AA 0901-WPA-0300 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Proposed Section BB 0901-WPA-0301 REV P0 Submitted Drawing received by the Local Planning Authority on 29 Jun 2026 - Site Location Plan 0901-WPA-0001 REV P1 Submitted Drawing received by the Local Planning Authority on 23 Jun 2026 - Existing and Proposed Block Plan 0901-WPA-0002 REV P1 Submitted Drawing received by the Local Planning Authority on 23 Jun 2026 - BNG Statement Report Rev P1, received by the Local Planning Authority on 01 Jul 2026 - Energy Statement Report Rev B, received by the Local Planning Authority on 23 Jun 2026 - DAYLIGHT & SUNLIGHT REPORT V1 Report, received by the Local Planning Authority on 15 Jun 2026 - HERITAGE STATEMENT Report, received by the Local Planning Authority on 15 Jun 2026 - NOISE IMPACT ASSESSMENT Report, 32295.PCR.01, received by the Local Planning Authority on 15 Jun 2026 - FIRE STATEMENT Report V1.2, received by the Local Planning Authority on 15 Jun 2026 - CONSTRUCTION MANAGEMENT PLAN Report pro-forma, received by the Local Planning Authority on 15 Jun 2026 - BIODIVERSITY STATEMENT Report, received by the Local Planning Authority on 15 Jun 2026 - SUSTAINABLE CONSTRUCTION CHECKLIST Report, received by the Local Planning Authority on 15 Jun 2026 - DESIGN & ACCESS STATEMENT Report Rev P0, received by the Local Planning Authority on 15 Jun 2026 - TREE SURVEY & ARBORICULTURAL IMPACT ASSESSMENT, Report, GHA/DS/160349:26, received by the Local Planning Authority on 15 Jun 2026
  6. The proposed development, as a whole, by reason of its siting, massing and relationship with the host building, would represent an overly dominant and incongruous form of development that would unacceptably erode the original appearance of the host property. The proposal would result in harm to the Central Richmond Conservation Area of which it forms part of, and there are considered to be no public benefits to outweigh this harm. As such, the proposal would be contrary to the NPPF, and the Local Plan policies 28 & 29, as supported by the Central Richmond Conservation Area Statement and Study.
  7. The proposed development, by reason of its siting, depth, height and massing would result in a form of development that lead to an unacceptable loss of light that would be detrimental to the amenity of the neighbouring occupiers. Therefore, the proposal is in conflict with policy 46 of the Local Plan.
