Adaptability is a crucial yet often misunderstood aspect of sustainable architecture. This study explores how adaptability can be systematically embedded from the early design phase through construction, use, and eventual transformation or repurposing. By conducting a comprehensive literature review, the research categorises adaptability into distinct types of change and examines their relevance at different project stages. The findings emphasise the necessity of incorporating adaptability considerations early in the process, ensuring that buildings can respond to evolving spatial, functional, and environmental demands over time. While existing research acknowledges the importance of adaptability, gaps remain in its practical application across the full building life cycle. This study addresses these gaps by proposing a methodology to support long-term decision-making and reduce obsolescence in the built environment. By promoting life cycle thinking, this paper contributes to a more comprehensive understanding of adaptability, advocating for strategies that enhance the longevity and sustainability of buildings while responding to future uncertainties.

Across Europe, declining school enrolment and a rapidly ageing population are producing a spatial imbalance in the public building stock: vacant or underused schools coexist with a growing demand for elderly care facilities. This study demonstrates that contemporary school buildings designed for adaptability can support long-term transformation into assisted living facilities when specific spatial and structural conditions are embedded early in the design process. Using a Norwegian architectural competition as a case study, a prototypical assisted living unit was developed from regulatory standards, procurement data, literature, and field observations. The school proposals were then analysed through plan overlay techniques, qualitative spatial mapping, and a criteria-based comparative assessment to evaluate their transformation capacity. The results show that regular structural grids, modular classroom geometries, distributed façades with adequate daylight access, and robust circulation systems significantly increase conversion feasibility, while compact forms and load-bearing wall systems constrain it. Proposals that ranked highest in short-term adaptability also demonstrated the greatest long-term transformation potential. The findings position adaptability not merely as spatial flexibility within an educational programme, but as a strategic design principle that extends building lifespan, supports resource-efficient public investment, and strengthens the resilience of municipal infrastructure.

Multistorey timber construction (MTC) is widely promoted for lowering embodied carbon, yet its uptake across Europe remains uneven. This study asks which drivers and barriers shape mid-rise wood buildings and how they differ across regions and stakeholders. We combine a structured literature review with a survey of 116 construction professionals across three deliberately contrasted national construction contexts. Belgium as an emerging market, Austria with a growing timber culture, and Norway as a mature policy-driven setting advancing timber. Respondents rated 31 literature-derived factors and 16 strategies. Across all contexts, respondents converge on a shared core: timber was perceived positively when it offered predictable project value, especially construction speed, image/marketing value, sustainability, and user-related benefits. Conversely, obstacles clustered around economic, technical, and legal uncertainty—especially building cost, fire performance, acoustics, conventional procurement, and path dependency. Country patterns suggest different priorities: Belgium may require increased ecosystem readiness, Austria standardisation and clearer regulatory interpretation, and Norway continued political support and market legitimacy. Stakeholder patterns further suggest differentiated support needs across architects, engineers, contractors, clients, suppliers, and verifiers. These findings explore MTC challenges and opportunities as contextual policy and industry priorities for empowering low-carbon construction and the circular economy transition in the built environment.
