Why it was refused

  1. The proposal would not comply with any exception within Paragraph 154 or 155 of the National Planning Policy Framework 2024, and therefore is considered inappropriate development in the Green Belt. The benefits of the proposal are considered to not clearly outweigh the harm to the Green Belt and amenity harm identified. The proposal would therefore not provide Very Special Circumstances in accordance with Paragraph 153 of the National Planning Policy Framework 2024. The development would fail to comply with Policy SADM26 of the Site Allocations and Development Management Policies Plan 2016, Policy CS13 of the Hertsmere Core Strategy 2013, and the National Planning Policy Framework 2024.
  2. The application fails to demonstrate that the proposal would not result in adverse impacts to neighbouring amenity in terms of noise disturbance to nearby sensitive receptors, and matters in relation to public safety, emergency response, and pollution and contamination in the event of a fire, have not been adequately addressed. The development would fail to comply with Policies SADM13, SADM20 and SADM30 of the Site Allocations and Development Management Policies Plan 2016, Policy CS16 of the Hertsmere Core Strategy 2013, and the National Planning Policy Framework 2024.

From the council's decision notice.
