Interior Design

Interior design is a multidisciplinary field that combines aesthetic sensibility with functional planning to shape built environments. At its core, interior design addresses the organisation of space, the selection and arrangement of furnishings and materials, and the orchestration of sensory stimuli—light, colour, texture, acoustics and temperature—to support human comfort, performance and well-being. Beyond decoration, it draws upon psychology, ergonomics, sustainability and cultural context to create settings that respond to diverse occupant needs, from private homes and workplaces to healthcare facilities and retail venues. Contemporary practice emphasises adaptable, resilient and evidence-based solutions that integrate digital simulation tools, participatory methods and post-occupancy evaluation. As demographic shifts, health concerns and environmental imperatives intensify, interior designers are exploring how spatial form and sensory quality can promote healthy ageing, equitable access, social cohesion and energy efficiency. In this way, interior design acts as both a creative and research-oriented endeavour, shaping the human-environment interface at scales from individual rooms to urban interiors.

Research on the built environment’s role in supporting vulnerable and ageing populations has called for new design paradigms that align spatial features with human physiology and perception. Foundational work argues that conventional architecture often overlooks the everyday impact of flooring, lighting, acoustics and spatial layout on autonomy and social participation. By reframing interiors as active agents in healthy ageing, researchers propose integrative frameworks that incorporate multisensory cues, flexible furniture systems and accessible circulation routes from the outset. This approach champions collaboration between architects, gerontologists and behavioural scientists to generate evidence-informed interventions that transform existing dwellings, care facilities and transport hubs into environments that prevent disability, enhance independence and promote wellbeing.

Field investigations into universal mobility in historic urban centres reveal that footpaths in five heritage cities often fall short of accessibility standards, owing to uneven paving, obstructed routes and inadequate curb transitions. These studies recommend context-sensitive retrofit guidelines for tactile wayfinding, ramp gradients and surface materials to bridge heritage conservation with universal access.

An empirical study of universal-design evaluation practices highlights a persistent tension between standardised checklists and holistic, multidisciplinary assessments. While checklists offer efficiency, stakeholders call for mixed-method audits—combining quantitative metrics with observational and user-feedback techniques—to capture the complex interplay of spatial form, user behaviour and environmental quality.

A “value-inclusive design” model introduces neighbourhood co-design workshops that embed social equity, resilience and environmental stewardship into urban interiors. Applied in an international student competition, this method demonstrates how participatory processes yield adaptive interior schemes—modular seating, biophilic partitions and community-shared facilities—that strengthen local identity, foster economic opportunity and nurture ecological awareness.

Technical terms

Accessible design: The practice of creating environments that can be used by people of varied abilities without specialised adaptation.

Inclusive design: A design philosophy that ensures spaces meet the needs of the widest possible range of users by considering human diversity in ability, age and circumstance.

Universal design: A framework for designing products and spaces to be inherently accessible to all people, to the greatest extent possible, without the need for modification.

Post-occupancy evaluation: The systematic assessment of a space after it has been used, to measure performance against design objectives and user satisfaction.

Value-inclusive design: A co-design approach that integrates social, economic and environmental values through stakeholder participation to create equitable and resilient interior solutions.
