The growing demand for sustainable and affordable housing requires construction systems that reduce material consumption, embodied environmental impacts, construction waste, and life-cycle costs while retaining the value of building components across multiple use cycles. This study presents a systematic scoping review and evidence map of circular economy strategies and reuse readiness in modular sustainable and affordable housing. A structured literature search covering publications from 2016 to 2026 identified 283 records, of which 49 studies were included following screening and eligibility assessment. The included studies were coded according to circular economy strategies within the 0R–10R framework, building life-cycle stages, modular technology typologies, sustainability and affordability indicators, and reuse-readiness attributes. The evidence map shows that the literature remains predominantly focused on life-cycle assessment, carbon emissions, waste reduction, reuse, and recycling. In contrast, early-stage circular strategies, including refuse, rethink, reduce, and redesign, as well as repair, refurbishment, remanufacturing, social value, life-cycle affordability, and operational reuse readiness, remain insufficiently examined. The findings further demonstrate that prefabrication or modularity alone does not ensure circularity. High reuse readiness depends on demountable connections, non-destructive disassembly, component standardization, durability, repairability, material traceability, reverse logistics, and credible second-life scenarios. Based on the mapped evidence, this study develops an evidence-informed Integrated Digital Circular Modular Ecosystem pathway that connects circular design, material passports, reuse-readiness assessment, BIM and digital twins, component grading, reverse logistics, circular marketplaces, and life-cycle performance evaluation. By integrating reuse readiness, life-cycle affordability, and digital traceability within a single evidence-informed pathway, the study provides a structured basis for researchers, policymakers, and industry stakeholders to evaluate and advance modular housing beyond construction efficiency toward long-term circularity and component value retention. As a conceptual synthesis, the pathway requires further validation through expert assessment and application to actual modular housing projects.
