Why it was refused

  1. The proposed first floor extensions, by reason of their size, siting, massing, design and prominent corner plot location, would result in a disproportionate, overly dominant and incongruous form of development that would fail to remain subordinate to the original dwelling. The development would be detrimental to the character and appearance of the host dwelling and the wider streetscene, contrary to Policies CDH01 and CDH05 of the Barnet Local Plan (2025), Policy D3 of the London Plan (2021) and the Council's Sustainable Design and Development Guidance SPD (2025).

From the council's decision notice.
