Why it was refused

The proposed sub-division of the property to form 2no. self-contained flats, by reason of its low PTAL 1b rating and distance to a station or town centre would fail to meet the criteria as set out for the sustainable redevelopment of larger homes. As such, the proposal would be contrary to the strategic aim to prioritise delivery of family homes from the existing housing stock and fail to accord with Policies CDH01 and HOU03 of the Barnet Local Plan (Adopted March 2025).
The proposed development, by reason of its inadequate internal floor-to-ceiling height for Flat B; poor internal layout and design and failure to provide adequate glazing and light for Flat A would result in a substandard quality of accommodation detrimental to the amenities of future occupiers. The proposal is therefore contrary to Policies D3 and D6 of the London Plan (2021); Policies HOU03, CDH01 and CDH07 of the Barnet Local Plan (Adopted March 2025); the Sustainable Design and Construction SPD (2016); and the Residential Design Guidance SPD (2016).

From the council's decision notice.
