Why it was refused

  1. The conversion of the single-family dwelling into two self-contained flats would result in the loss of a single family unit which is of high priority in the Borough. The proposal would fail to re-provide a 3-bed family unit and fail to meet the criteria as set out for the sustainable redevelopment of larger homes, to the detriment of the strategic aim to prioritise delivery of family homes, and mitigate the erosion of larger homes from within the existing housing stock in the Borough. The proposal would be non-compliant with Barnet's Local Plan Policy HOU03 as the existing dwelling is below 135 sqm of gross internal floor area and the proposed units would be below 61 sqm. As such the proposal is contrary to policy HOU02 and HOU03 of the Barnet Local Plan (2025) and Sustainable Design and Development Guidance SPD (2026).
  2. The proposal would result in substandard accommodation for the future occupiers, due to the proposed 2 bed 3 person ground floor unit not meeting the minimum gross internal floor area, and failing to provide the minimum floor to ceiling to height of 2.5m for the first floor unit. The vertical stacking of rooms of the ground floor and first floor unit is unacceptable due to living room of first floor being placed on bedroom of ground floor unit. The proposal is considered contrary to D3 and D6 London Plan (2021), Policy CDH01 of Barnet Local Plan(2025) and Sustainable Design and Development Guidance SPD (2026).
  3. The proposed single storey rear infill extension due to excessive depth of 3.7m along the common boundary will be overbearing and will increase the sense of enclosure for the attached property no.102, detrimental to their amenity. The proposal is contrary to Policy D3 of the London Plan (2021) and Policies CDH01 and CDH05 of the LB Barnet Local Plan (March 2025), and Sustainable Design and Development Guidance SPD (2026).
