“The Sustainable Movement Corridor, due to the extent and proximity to the grade I listed St James the Great church, will cause less than substantial harm, at the lower end of the scale, to the heritage asset, which will significantly and demonstrably outweigh the benefits of the Sustainable Movement Corridor element of the proposed development. This is contrary to paragraph 215 of the National Planning Policy Framework (December 2024); and…”
