Why it was refused

  1. Due to the design of the building, the uses proposed and the existing facilities available on site, insufficient justification has been provided to demonstrate to the satisfaction of the Local Planning Authority that the building is reasonably required for the purposes of agriculture. Therefore the development would result in unjustified new built development in the open countryside contrary to criterion (a) of Policy RE4 of the Adopted Monmouthshire Local Development Plan
  2. No Drainage Statement has been provided and a suitable surface water drainage destination has not been demonstrated. In the absence of sufficient information, it is not possible to determine whether sound surface water drainage arrangements are achievable. Therefore the proposed development would be contrary to Technical Advice Note (TAN) 15: Development, flooding and coastal erosion (2025) as well as Policies SD4 and RE4 (b) of the Adopted Monmouthshire Local Development Plan.
  3. The applicant has failed to submit sufficient ecological information to allow the Local Planning Authority to fully assess the likely effects of the proposed development on biodiversity, ecological networks, and the resilience of ecosystems. In the absence of sufficient survey work, the Local Planning Authority cannot be satisfied that the proposal complies with the relevant requirements of Policy NE1 of the Local Development Plan and Planning Policy Wales (PPW Edition12, 2024), Chapter 6: Distinctive and Natural Places.
  4. The applicant has failed to submit sufficient information in order to undertake a Habitats Regulations Assessment (HRA) as required by the Conservation of Habitats and Species Regulations 2017 and to fulfil duties under the Wildlife and Countryside Act 1981 and the Environment (Wales) Act 2016. Furthermore, Insufficient information has been provided to enable the Local Planning Authority to assess the potential impacts of the proposal on Sites of Special Scientific Interest (SSSIs), having regard to its duties under Section 28G of the Wildlife and Countryside Act 1981 (as amended), and on locally designated sites, including Sites of Importance for Nature Conservation (SINCs), in accordance with Planning Policy Wales (Edition 12, paragraphs 6.4.5 and 6.4.6).
