This study examines modular construction practices in Mainland China, Hong Kong, and Singapore, as well as data-driven smart city innovations in London and Barcelona, focusing on urban sustainability. Mainland China uses central supply facilities and BIM to boost housing output. Hong Kong employs modular construction for high-density living, and Singapore leverages PPVC with state support to enhance efficiency. London excels in ICT infrastructure for data management, while Barcelona leads in data-oriented competencies. Despite high upfront costs and logistical challenges, these innovations significantly enhance sustainable urban development. Recommendations include government incentives, education, centralized supply chain management, and updated building codes. Future research should explore long-term impacts, sociological implications, and AI, IoT, and blockchain integration in urban management.
