Evaluation of spaciousness in isolated and confined environments

This thesis explores the adverse psychological effects of Isolated, Confined, and Extreme (ICE) environments, aiming to explore the correlation between these effects and interior architectural elements. In addition, several methods are tested to evaluate interior architectural elements that may directly impact the perceived spaciousness of these environments. The initial phase of the thesis examined the effects of the COVID-19 pandemic on the perception of interior spaces. Individuals who found their living spaces visually appealing, engaged in various activities, expressed satisfaction with their connections to outdoor spaces, encountered less boredom, and displayed fewer signs of anxiety and psychological distress. The following phase explored the effects of furniture, lighting, surface texture, and ceiling height on spaciousness perception and surveyed emotional and aesthetic responses to various design factors. The results indicated that interior architectural elements have a relatively minor impact on individuals' spatial perception within a habitat. Design training is a more significant influencer in all spatial evaluations than interior architectural elements. Although furniture, lighting, and texture have statistically significant effects on spaciousness and aesthetic judgments, design training remains a substantial moderator of these effects. This research contributes substantially to comprehending the complex dynamics between interior architectural design and human perception. The findings underscore the profound influence of design choices on practical functionality and emotional experiences within confined spaces. The study's implications extend to architects, designers, and policymakers, providing valuable insights for enhancing psychological well-being in ICE environments.
