Abstract The rapid aging of public rental housing stock in Seoul necessitates scalable and context-sensitive redevelopment strategies. Off-site construction (OSC) offers a promising solution for minimizing on-site disruption while enabling efficient modular building processes. However, diverse and irregular site conditions in urban areas often limit its practical application. This study proposes a site condition-equipment integrated OSC framework that aligns modular construction techniques with site-specific constraints. Housing lots are classified by attributes such as size, shape, and road access, with corresponding equipment and module types identified for each category to evaluate OSC feasibility. Special attention is given to Seoul’s small-lot housing clusters, where phased, cluster-based redevelopment is recommended to enhance efficiency and cost-effectiveness. A three-stage implementation roadmap is presented: lightweight OSC for small lot clusters; lot consolidation for mid-sized modules; and hybrid OSC for larger or merged sites. The proposed framework supports modular renovation efforts by improving adaptability, scalability, and operational viability in the renewal of aging public rental housing.
