The Overlooked Significance of Interior Architecture in Shaping Human Experience
In contemporary architectural discourse, an enduring challenge persists: the tendency to prioritize external aesthetics over internal functionality and experience. Despite decades of discussions centered on how people interact with and inhabit spaces, architectural value is frequently judged from the exterior. This phenomenon, exacerbated by the prevalence of social media platforms like Instagram, transforms buildings into mere objects for visual consumption. In this landscape, the outer shell often becomes the primary canvas for designers, while interior architecture—the very core of daily life—is relegated to a secondary or supplementary role, viewed as an extension of a long history of decorative elements being undervalued in design.
Reimagining the Significance of Inner Architectural Spaces
The disparity in appreciation between a building's facade and its interior is particularly evident in the realm of transportation and civic structures. These are environments traversed by millions daily, including terminals, stations, concourses, and expansive halls. Such spaces exert a more consistent influence on human perception and behavior than any exterior ever could, yet they continue to be consistently undervalued within the architectural community. This isn't merely a matter of subjective preference; it represents a fundamental failure to acknowledge their profound impact. Recognizing this gap, Architizer's A+Awards actively champions interior design through categories such as Transport Interiors, Sustainable Interior Project, and Best Interior Design Firm.
For too long, the architectural field has been captivated by the allure of iconic structures, conditioning both practitioners and the public to engage with buildings from a distance. Within this paradigm, silhouettes and grand, singular images serve as easily digestible symbols, while interiors—experienced dynamically over time—defy simple representation. This framework often reduces interior architecture to an implementation phase rather than a conceptual one, merely a response to functional requirements after the primary structure is in place. Even when interior strategies are pivotal to a building's operation, the credit tends to accrue to the external form, rather than the intricate internal environment, a hierarchy deeply entrenched in large-scale public edifices like airports and railway stations.
The experiences within a building are what truly matter. Transport interiors, perhaps more than any other typology, vividly demonstrate the limitations of an exterior-centric approach. These spaces are designed for continuous occupation, not occasional visits. They must perform under pressure, accommodate unforeseen circumstances, and guide individuals who are often fatigued, pressed for time, or disoriented. Projects such as the Harvey Milk Terminal 1 at San Francisco International Airport exemplify how interior architecture fulfills crucial civic functions. Here, the clarity of space and the infusion of natural light are not merely aesthetic choices but essential operational tools. The building's effectiveness is not dictated by its outward appearance, but by how skillfully movement is choreographed through its internal design. Other firms, like DA Bureau, push the boundaries further, conceiving interior spaces as immersive realms where light, sound, and material textures converge to create unique sensory experiences. In these contexts, interiors transcend subordination; they embody the very essence of the architecture, transforming facades into mere entry points.
The undervaluation of interior architecture extends beyond transportation hubs to civic buildings. While these structures are often lauded for their external grandeur, their interiors are frequently perceived as neutral containers. However, it is within these interior spaces that public life unfolds: where people assemble, wait, move, and interact. Sydney's new Central Station serves as a potent reminder that civic identity is forged through a sequence of interior experiences as much as by its urban presence. Its cultural significance is carried by its halls, passages, and thresholds—spaces that manage scale and movement while fostering a collective sense of orientation. These are not incidental zones; they constitute the building's public heart. Even at a more intimate scale, as seen in Krume Bäcker, interior architecture shapes how buildings are perceived and remembered, crafting identity through an experience tailored to the human body rather than the distant skyline.
A significant part of the problem lies in the professional classification of interior architecture, often viewed as a specialization rather than a distinct discipline—a subset of architecture rather than a fundamental mode of architectural thought. This is vividly illustrated by firms like Alvarez Sotelo Arquitectos, whose residential renovations treat interiors as integral architectural systems rather than mere surface treatments. Through precise spatial reorganization, adjusting alignments, circulation paths, and degrees of enclosure, their projects demonstrate that interior architecture can redefine how space is understood and inhabited without relying on formal spectacle. Practices like Linehouse further challenge the traditional hierarchy by showing how material intelligence and spatial continuity can convey architectural intent up close. Their work emphasizes cultural specificity through atmosphere, creating uniquely defined spaces through their interiors. These approaches are vital because they resist object-centric thinking, instead highlighting the importance of architectural intelligence at a human scale, prioritizing continuity over novelty and experience over static imagery. Yet, interior work is still often celebrated in isolation, reinforcing the misconception that it holds importance, but not paramount significance.
This hierarchy between exterior and interior has tangible consequences, particularly concerning sustainability. In many building types, environmental performance is as much a result of interior decisions as it is of envelope design. Factors such as natural light penetration, material selection, spatial density, and adaptability all profoundly influence long-term resource consumption. In transport and civic interiors, these factors are amplified due to large volumes, extended operating hours, and fluctuating occupancy, placing immense demands on environmental systems. Interior architecture mediates these conditions daily, often unseen. Nevertheless, sustainability narratives frequently prioritize facades and technological solutions over inherent spatial intelligence. This perpetuates the belief that interiors are temporary or expendable, rather than fundamental to a building's enduring performance. The work of Multitude of Sins exemplifies this understanding, addressing material economy through reuse and minimal intervention, embedding sustainability directly into their architectural approach rather than treating it as a technical add-on.
Awards, though sometimes dismissed as merely symbolic, wield structural influence. They shape what is perceived, valued, and pursued within a field. When interior architecture is relegated to a secondary status, the profession inherently adopts this hierarchy. This matters profoundly because interior architects are integral to the profession. They navigate stringent constraints, manage complex programs, and craft environments that must perform continuously. Their work is no less architectural because it is internal; indeed, it is often more demanding. Recognition does not inflate the importance of interior architecture; rather, it grants it essential visibility.
The ramifications of this imbalance become particularly evident in major transport hubs. Interiors such as the expansion of Terminal 5 at O’Hare International Airport represent some of the most intricate architectural environments in contemporary practice. They are required to function continuously, adapt to evolving security protocols, and accommodate vast movements of people over extended periods. Yet, their architectural intelligence—the spatial sequencing, environmental control, and organizational clarity that enable their operation—rarely receives the same cultural weight as external form. When projects of this magnitude are discussed primarily as infrastructure rather than architecture, the discipline implicitly relinquishes one of its most challenging arenas.
The dominance of the iconic persists because it offers immediate recognition and marketable imagery. However, if architecture's ultimate purpose is to shape human experience, then interiors demand deeper consideration. These are the spaces where architecture's cultural relevance is most rigorously tested, where the discipline has the opportunity to demonstrate its capacity to manage complexity and, often, sustain public life. Interior architecture, especially in transport and civic contexts, is where architecture's social, environmental, and operational intelligence most clearly converges. From terminals and stations to adaptive reuse projects and large-scale public environments, these ambitious endeavors necessitate rigorous, long-term thinking. By championing interior architecture alongside various building typologies, recognition frameworks can accurately reflect how architecture is truly experienced—not just how it is perceived—thereby elevating work that fundamentally shapes daily existence.
