The historical separation of port and urban functions has resulted in fragmented spatial structures, restricted access, and conflicts between operational requirements and urban development priorities. This article examines multifunctional facilities as instruments of compact port-city development. It investigates how buildings and infrastructural complexes can integrate logistics, mobility, maritime services, research, commerce, public amenities, and environmental systems while maintaining seaport safety and operational continuity. The study combined a structured literature review, functional-spatial analysis, and interpretation of port-city and waterfront transformations. It focuses on port-city relations, hybrid infrastructure, functional compatibility, and interactions with the urban and natural environment. The proposed framework positions multifunctional facilities as strategic port-city interfaces that improve land-use efficiency, connectivity, adaptability, and waterfront accessibility without displacing essential water-dependent activities, thereby contributing to compact, sustainable, and resilient structures. %@ 2083-6473 %R 10.12716/1001.20.03.13
