Why it was refused
- The proposed development by reason of its siting, size, scale and design would be an undesirable addition both spatially and visually and is considered inappropriate development in the Green Belt, for which no very special circumstances have been put forward and would be harmful to the openness of the Green Belt. The proposal would therefore be contrary to the NPPF (2025), policy G2 of the London Plan (2021), Policies CDH01, CDH05 and ECC06 of Barnet's Local Plan and the Sustainable Design and Construction Guidance Supplementary Planning Document (2026).
From the council's decision notice.
