This paper investigates the relationship between the typological organisation of residential interiors and the subjective experience of spatiality, formed through sequential, visually mediated movement. It examines whether perceived spatiality derives primarily from the mental integration of the dwelling as a whole through circular movement, or from immediately accessible visual relationships such as visual accessibility and perceptual depth. An experimental study was conducted in which participants with and without professional education in architecture and interior design evaluated four typologically distinct residential interior models (circular circulation, enfilade, branched structure, and open plan), presented through standardized screen-based animated walkthrough simulations designed to replicate continuous spatial movement under controlled visual conditions. Subjective evaluations were collected using eight bipolar semantic scales. Analysis of variance showed that typological structure had a statistically significant effect on all analysed dimensions of spatiality, while professional expertise did not produce significant differences. The results support the hypothesis that perceived spatiality is predominantly shaped by immediate visual accessibility and perceptual depth rather than by circular spatial connections requiring sequential cognitive integration. The findings clarify key perceptual mechanisms of spatiality and underscore the distinction between spatial flow as a structural property and spatiality as a perceptual category, with implications for residential design and further research.
