The article explores the concept of dormitory housing as a distinct architectural and typological category in contemporary architecture and defines its role in shaping a new paradigm of residential environments in the 21st century. The historical origins and evolution of dormitory spaces are analyzed, tracing their transformation from monastic sleeping quarters and educational institutions to modern multifunctional residential complexes that combine private and shared areas. The main development trends of this typology are outlined in the context of dynamic socio-economic transformations, globalization, and increasing population mobility. Fundamental architectural and planning principles of dormitory housing are identified, including the integration of private and communal spaces, flexibility of internal spatial organization, ergonomic planning solutions, modularity, and functional adaptability. Particular attention is paid to the social role of dormitory housing as a factor in community formation, the development of horizontal social connections, social integration, and the improvement of residents’ quality of life. Urban planning aspects of dormitory housing integration into the urban fabric are examined, focusing on its interaction with surrounding infrastructure, its influence on spatial city organization, and its potential as an element of polycentric urban development. A comparative analysis with traditional dormitories and collective housing structures highlights the distinctive features, competitive advantages, and strategic prospects of this typology. The study concludes that dormitory housing represents a promising model of co-living space capable of addressing contemporary challenges of urbanized society, fostering social integration, and providing a new quality of residential environment in 21st-century architectural practice.
