The Future of Historic Buildings: How do conservation architects use digital tools to better maintain historic buildings? Part 2 Dissertation 2025 Flynn McGee London School of Architecture | UK My research is a critical analysis of how modern techniques of Building Information Modelling (BIM) can support historic conservation philosophies in the challenge to manage a significant public building.Through analysing the working documents for the patent slate roof restoration at the Palace of Westminster, I investigate the practical challenges of budget, risk, and sequencing that arise when striving for a more environmentally conscious, proactive repair and maintenance strategies that addresses material scarcity.This critiques not only the digital processes within my practice’s operation for maintaining historic buildings, but also explores how these might be deployed to address the challenges arising in the context of reduced resources for public capital projects.My methodology of analysing construction details and workflows across different stakeholders, enabled me to gain a greater insight into the tensions between designing for maintenance to improve operational energy, and the need to enhance and respect materials of historic significance.The resulting research identifies a gap in guidance on BIM for heritage buildings, and an opportunity to apply knowledge from this project to support the creation of digital twin compliance codes as a way of preserving cultural and architectural authenticity, whilst addressing the recommendations of the Hackitt Report.
