Adaptation is the process of altering, modifying, or extending a building due to changes in its intended use without the intent to replace the design (Douglas, 2006). Adaptation is vital because, with climate change, embodied carbon, demolition waste, and built environment resilience to environmental hazards in the future, decrease (Pacheco-Torgal and Goran-Granqvist, 2023). Reuse encourages the systems approach that is integrated and takes care of the ecological performance, heritage value, and social benefit (Cotgrave and Riley, 2013). A case study of three UK precedent conversions, Tate Modern, Gasholders London, and the Tobacco Factory, is used to identify whether the benefits, challenges, and technical decision-making of structural adaptation choices prevail, hinder, or have no effect on existing-building reuse. In such a way, the remedial action, feasibility analysis, and long-term sustainability objective are balanced by context-specific structural methodology that facilitates the adaptive reuse. Theoretical and Methodological Framework Adaptive reuse is commonly known to be more sustainable than demolition and new-build development due to its ability to sustain embodied energy, lessen construction wastefulness, and also retain the social and cultural worth of the existing structures. Cotgrave and Riley (2013) consider the sustainability of the built environment to be a triple-bottom-line system where all three environmental, social, and economic factors are to be tackled as a combination. Structural fabric preservation means it is not required to spend so much on carbon to extract and rebuild the materials, or to maintain continuity of place and identity. Technically, Doran, Douglas, and Pratley (2009) state that to refurbish and adapt a building, a completely different attitude should be taken to a new one since the old buildings quite often harbor undiscovered flaws, outmoded materials, and non-standard work that should be well comprehended before any interference. This essay uses a precedent-based method of analysis based on the feasibility and options appraisal model by Watson (2009). This model promotes the systematic choice that should be made to decide on whether adaptation is better than new build based on structural condition, risk, cost, regulatory constraints, and long-term performance. All case studies are thus analysed using three analytical dimensions: benefits, here sustainability outcomes and regeneration outcomes, challenges, here structural constraints and compliance issues, and ethos or structural logic, here referring to the design and engineering philosophy behind intervention. It is a framework through which a unitary and critical comparison of the varying adaptive reuse strategies can be drawn across the chosen precedents. Case Study 1 – Tate Modern (Bankside Power Station → Museum) A prime example of large-scale adaptive reuse where the existing building remained the primary source of architectural form and spatial experience is the conversion of Bankside Power Station into the Tate Modern. Herzog and de Meuron, with Arup as structural engineer, made the strategy to focus on the existing Turbine Hall as a public void, with a series of new gallery floors, circulation routes, and building services to be incorporated within the original steel-and-brick envelope. This strategy is consistent with the principle of minimal intervention of Douglas (2006), in which the existing structure is used based on its inherent capacity and nature instead of substituting...
