This paper examines the concept of negative space in architecture, with the aim of determining its structural, perceptual, and organisational roles within architectural composition. The study addresses the lack of a unified theoretical framework in which negative space is treated as an active architectural element rather than a residual by-product of form. The central hypothesis of the research is that negative space becomes architecturally meaningful only when it possesses clearly defined geometric boundaries, perceptual legibility, and an organisational role within the composition. These conditions enable its recognition as an active component of architectural structure. The paper develops a framework that integrates formal, phenomenological, and perceptual interpretations of the relationship between solid and void. The methodology relies on qualitative analysis of selected architectural examples, evaluated through criteria that distinguish three positional types of negative space: internal, peripheral, and external negative space. The findings confirm the hypothesis, demonstrating that negative space influences spatial hierarchy, visual clarity, and ambient qualities, and therefore operates as a formative principle rather than a passive absence. The study further identifies limitations of the concept, particularly in dense urban contexts and in culturally diverse models of spatial perception. These observations indicate the need for future empirical work focused on user perception and applied case studies. The paper thus provides a coherent basis for advancing methodological tools and for incorporating negative space more systematically into contemporary architectural design practice.
