Additional challenges include groundwater flood risk, Grade 3 agricultural land classification, and the need to relocate an agricultural shed to preserve views of 17th-century buildings. Key elements of the development include: The Farmhouse A historical stone barn A new build residential unit The rebuild of the current bungalow Balancing heritage conservation, modern functionality, and environmental responsibility, while meeting NPPF and Cornwall Local Plan requirements has required careful phasing, early engagement with conservation officers, and a design approach that celebrates authenticity while enabling future-focused innovation. Early and proactive engagement with heritage and planning authorities is essential. Listed building consent processes highlight the importance of detailed significance assessments and clear justification for any interventions. Investigative works revealed extensive damp issues, reinforcing the need for thorough condition surveys before design development. The Polglaze Estate highlights the importance of integrating sustainability narratives into heritage schemes, demonstrating that modern energy solutions and traditional aesthetics can coexist. Collaborative design workshops help reconcile conservation priorities with functional requirements, ensuring that new-build elements respect the AONB context. Phasing strategies are critical, advancing the manor and bungalow first enable early wins while allowing time for complex barn and new-build approvals.
