Planning Decision
Why it was refused
- 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 a Biodiversity Net Gain Assessment and statuary metric 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 Policy ECC07 of the Barnet Local Plan (adopted March 2025).
From the council's decision notice.
