The desk-based research and heritage assessment were undertaken in accordance with the relevant Chartered institute for Archaeology (CIfA) and Historic England (HE) guidance. The historic building appraisal was conducted by E. Wapshott and A. Allen in April 2022 (see SWARCH 2022). The building appraisal followed guidelines laid down in CIfA's Standard and Guidance for the Archaeological Investigation and Recording of Standing Buildings or Structures (2020) and Historic England's Understanding Historic Buildings: A Guide to Good Recording Processes (2016). The site was visited in February 2024 by E. Wapshott and F. Balmond and a reappraisal of the buildings in their current condition was undertaken. Photographs of the site were taken and are included in this report (see Appendix 1). Updated Assessment 2025 - It is considered that of all of the buildings at Hustyn Mine Park, the much-extended main house represents the lowest heritage value element owning to its much-altered elevations, with significant change having taken place in the last 30 years. The mill building still reads, mostly from the outside, as a coherent 19th century mill structure, with its extant wheel pit and fragments of water wheel. The west cottage, although also much altered, still comprises much of the structure shown on the tithe map. As such whilst all three buildings are considered as non- designated heritage assets of local value, contributing to the narrative of the development of this landscape in the 19th century, it is the main house contains the most flexibility for change. It is therefore considered that if consent for demolition was granted, suitable mitigation would take the form of building recording of the structures during demolition, which has the potential to offer a greater understanding of the original form and construction date of the phases of these buildings. Any replacement dwelling should seek to maintain the rural aesthetic through the utilisation of local vernacular styles and materials, making reference to relevant local design guidance and polices.
