Abstract
<jats:p>The article considers current approaches to the formation of residential space in the context of rapid urbanization and increasing demands for the quality of the living environment. The growing concentration of population in urban areas intensifies the need for rational use of space, higher functional efficiency, and the ability of housing to adapt to changing social and economic conditions. In this regard, the concept of smart planning is considered as a relevant framework that integrates technological, spatial, and managerial solutions aimed at improving the performance of residential environments. Particular attention is given to the necessity of combining technical, economic, environmental, and social dimensions within a unified analytical approach. The study emphasizes the importance of multi-criteria assessment as a tool for capturing the complexity of housing design and planning decisions. Such an approach allows for the simultaneous consideration of measurable indicators, including cost parameters, energy consumption, and spatial efficiency, alongside qualitative characteristics such as comfort, privacy, and adaptability. The paper also highlights methodological challenges associated with the evaluation of heterogeneous indicators. A key issue lies in the integration of quantitative data and qualitative attributes into a coherent system of analysis. This requires the application of normalization techniques, the development of appropriate evaluation scales, and the justification of weighting coefficients that reflect the relative importance of different criteria. The need for balancing objectivity and expert judgment is emphasized, particularly in the context of assessing social and behavioral aspects of residential space. The relevance of this research is reinforced by the transition toward sustainable urban development, where housing plays a central role in shaping environmental performance, social well-being, and economic efficiency. The transformation of traditional housing models and the emergence of compact and flexible residential formats increase the demand for advanced evaluation methodologies that can support informed decision-making in planning and development processes. Overall, the study outlines the conceptual foundations for improving the assessment of residential space within the smart planning paradigm and identifies key directions for further methodological development in the context of sustainable urban systems.</jats:p>
