The journal presents the discourses on interiority from multiple perspectives in various design-related disciplines: architecture, interior design, spatial design, and other relevant fields. The idea of interiority emphasises the internal aspects that make and condition the interior, which might be understood and manifested through the users’ inhabitation, through the materiality of objects and built environment as well as through specific methods and approaches of design practice. The journal addresses the idea of interiority as both experienced and practised, which might be examined through theoretical discussion, spatial design practice and empirical interior research.
