Why it was refused

  1. The proposed extensions, by reason of their cumulative size, siting, appearance and design, would appear as a disproportionate addition which would not respect the design and appearance of host property. The development would therefore be detrimental to the character and appearance of the host property, contrary to Policy D3 of the London Plan (2021), Policy CDH01 of the Barnet Local Plan (March 2025), Policy CDH05 of the Barnet Local Plan (March 2025), Policy D3 of the London Plan (2021) and the Council's Sustainable Design and Development Guidance SPD (2026).

From the council's decision notice.
