Why it was refused

The proposed development given the cumulative scale, footprint and siting of the extension would result in an incongruous form of development that would erode the historic plan form and spatial arrangement of the listed building, deviating from the original design and character of the listed building to the detriment of the character, appearance and design of the conservation area and the listed building. The proposal therefore would create less than substantial harm to the host dwelling, the conservation area and fail to comply with the objectives of the Listed Building Sections 16(2) and 66(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990, paragraph 215 of the National Planning Policy Framework (2025), policies HC1, D3 and D4 of the London Plan (2021), policies 7B, 7.4, and 7C of the Ealing Development Management DPD (2013), Policy DAA of Ealing's Local Plan (Reg.22), Ealing Housing Design Guidance (2022), Bedford Park Conservation Area Addendum and Ealing's Generic Management Plan for Conservation Areas (2023).

From the council's decision notice.
