Why it was refused
- The proposed development, by reason of its design and scale, would fail to respond appropriately to the established character of the surrounding residential area. In particular, the excessive rearward projection at ground and first floor levels would result in a disproportionate structure, while the contemporary design of the front elevation would appear incongruous within the predominantly traditional streetscape of this prominent corner site. As a result, the proposal would cause harm to the character and appearance of the area, contrary to Policies CDH01 and CDH06 of the Barnet Local Plan, the Barnet Residential Design Guidance SPD, and Policies D1, D3 and D6 of the London Plan.
- Insufficient ecological and Biodiversity Net Gain (BNG) information has been submitted to enable the Local Planning Authority to fully assess the impact of the proposal on biodiversity and protected species. In particular, the absence of a Preliminary Roost Appraisal and clarity regarding habitat and hedgerow loss prevents a determination of compliance with Biodiversity Net Gain requirements. As such, the proposal fails to demonstrate compliance with relevant biodiversity legislation and planning policy contrary to Policy G6 of the London Plan (2021) and Policies ECC07 (Biodiversity) (adopted March 2025).
- The proposed development by reason of its scale and design would appear overbearing and visually intrusive, when viewed from the rear gardens of no.40 Lullington Garth. The proposal would therefore be contrary to Policy D3 of the London Plan (2021), Policy CDH01 of the LB Barnet Local Plan (2025), the Sustainable Design and Construction SPD (2016) and the Residential Design Guidance SPD (2016).
From the council's decision notice.
