The Interfusion: Mobile Performance Architecture Reconnecting Art and Public Space

Project by Ömer Seçim and Barkin Karabas

The Return of Art to the Street Through Mobile Performance Architecture

In contemporary cities, public art is increasingly pushed into controlled interiors, curated galleries, institutional theaters, and commercial cultural venues. While architecture has historically played a major role in shaping collective experiences, modern urban regulations often limit the spontaneous interaction between art and the public realm. “The Interfusion” challenges this separation through a bold proposal rooted in mobile performance architecture, temporary urban infrastructure, and adaptable public space design.

Designed by mer Seçim and Barkin Karabas, The Interfusion reimagines the relationship between artists, audiences, and the city itself. The project introduces a deployable performance structure capable of transforming streets and plazas into flexible cultural stages. Positioned within the urban fabric of Madrid, the proposal responds directly to the restrictions placed on street artists and performers through city regulations that constrained public artistic expression.

Rather than treating performance as an isolated event inside enclosed venues, The Interfusion proposes a new architectural language where mobility, adaptability, and openness become central spatial values. The project becomes more than a temporary stage. It evolves into an urban catalyst capable of reconnecting citizens with culture in the spaces they inhabit every day.

Reclaiming Public Space Through Adaptive Urban Design

One of the strongest architectural themes within The Interfusion is its understanding of public space as a living social environment. The proposal recognizes that streets, plazas, and open civic environments are not merely circulation routes. They are spaces where collective memory, identity, and conversation are formed.

The project was developed in response to regulations introduced by Madrid’s city council in 2014, which imposed strict limitations on street performances. Amplifiers were restricted, performance durations were controlled, and artists were required to receive official permission before presenting work in public spaces. These regulations significantly reduced the presence of spontaneous street art within the city.

The Interfusion responds critically to these constraints through architecture. Instead of opposing regulations directly, the project adapts to them through a carefully engineered mobile structure. Its dimensions are optimized for transportation and temporary installation, allowing the system to move efficiently through the city without creating permanent disruptions.

This adaptability reflects a larger architectural question concerning the future of temporary urban infrastructure. As cities become denser and more regulated, flexible architectural systems capable of responding to changing urban conditions become increasingly relevant. The Interfusion demonstrates how temporary structures can activate underused public spaces while maintaining sensitivity toward surrounding urban environments.

Mobile Architecture as a Platform for Cultural Inclusivity

At the conceptual core of The Interfusion is the belief that art should remain accessible to everyone. The project rejects the idea that artistic experiences belong exclusively within elite cultural institutions. Instead, it positions architecture as a mediator capable of dissolving barriers between performers and everyday urban life.

The structure functions as a mobile cultural platform accommodating multiple forms of artistic expression. Through its folding and expandable system, the performance space adapts according to event scale and performance type. This flexibility allows musicians, performers, and interdisciplinary artists to occupy the same architectural framework in different ways.

The project’s modular organization is particularly important from an architectural standpoint. Rather than designing a fixed pavilion with predetermined functions, the proposal introduces a dynamic system capable of transformation. The architecture becomes responsive instead of static.

This approach aligns with broader contemporary discussions surrounding adaptive architecture and multifunctional public infrastructure. In many cities, permanent cultural buildings require significant economic investment and remain spatially rigid. The Interfusion proposes a lighter and more flexible alternative capable of bringing cultural programming directly into neighborhoods and urban streets.

Its mobility also reinforces the democratic nature of public art. Instead of requiring audiences to travel toward institutions, the architecture itself travels toward the public.

Architectural Form and Spatial Configuration

Visually, The Interfusion combines industrial modularity with lightweight membrane systems. The architectural language balances technical efficiency with spatial openness, creating an environment that feels both temporary and immersive.

The structure is composed of modular steel-framed units capable of unfolding into larger spatial configurations. These components create elevated performance zones, circulation areas, and acoustic enclosures while maintaining visual transparency toward the surrounding city.

The deployable skin system contributes significantly to the project’s identity. Curved membrane surfaces soften the rigid structural framework and create a semi-transparent envelope around the performance zone. During nighttime events, the illuminated membrane transforms the installation into a glowing urban landmark visible across surrounding public squares.

The proposal demonstrates careful consideration of both practical construction and experiential atmosphere. Materials such as ETFE, polypropylene, polycarbonate, ABS, and lightweight steel components were selected based on durability, transportability, and acoustic performance.

This material strategy reflects the project’s broader architectural ambition: to create a structure that is simultaneously lightweight, mobile, durable, and visually engaging.

Temporary Architecture and Urban Flexibility

Temporary architecture has become increasingly significant within contemporary urbanism. Cities today require spaces capable of responding quickly to social, cultural, and environmental shifts. The Interfusion addresses this need by proposing an architecture that exists in motion rather than permanence.

Its temporary nature allows it to activate multiple urban conditions throughout Madrid. From historic plazas such as Plaza Mayor to neighborhood squares like Plaza de Lavapiés and Plaza de Tirso de Molina, the structure adapts to diverse urban contexts while preserving the character of each location.

This mobility creates new opportunities for cultural decentralization. Instead of concentrating artistic events in designated districts, the project distributes cultural experiences across the city. The architecture therefore becomes a tool for social accessibility and urban inclusivity.

The proposal also demonstrates how temporary interventions can create strong emotional and spatial impact despite their non-permanent status. Through lighting, performance, movement, and audience interaction, The Interfusion transforms ordinary public spaces into immersive collective experiences.

The Relationship Between Performer and Observer

An important conceptual dimension of The Interfusion lies in its exploration of interaction between artist and observer. The project draws inspiration from the belief that meaning is created collectively through participation and interpretation.

This idea is reinforced spatially through the open configuration of the structure. Audiences are not separated from performers through rigid architectural boundaries. Instead, the project creates layered relationships between spectators, performers, circulation routes, and the surrounding city.

The architecture encourages proximity and shared experience. It transforms observation into participation.

By dissolving the conventional distinction between stage and street, the project establishes a more inclusive cultural environment. Public space itself becomes performative. The city becomes part of the artistic experience.

This architectural approach reflects contemporary discussions surrounding participatory urbanism, where users actively shape spatial meaning rather than passively consuming it.

Environmental and Acoustic Considerations

Despite its expressive visual identity, The Interfusion also responds carefully to practical urban concerns. Acoustic control was an important factor within the proposal due to the regulatory challenges associated with public performances in Madrid.

The deployable membrane system helps contain and direct sound while reducing disturbance toward nearby residential environments. This strategy demonstrates how architecture can mediate tensions between cultural activity and urban regulation.

The lightweight material palette additionally minimizes structural weight and transportation impact. Components were designed for efficient assembly, disassembly, and mobility.

This emphasis on resource efficiency aligns with larger architectural conversations surrounding sustainable temporary infrastructure. Instead of creating large permanent buildings with limited flexibility, The Interfusion proposes a reusable and adaptable cultural system capable of evolving across different locations and events.

Architecture as Social Conversation

The Interfusion positions architecture as an instrument for dialogue. The project argues that art should not remain hidden behind institutional walls or accessible only to select audiences. Instead, culture should exist openly within the rhythms of everyday urban life.

This perspective becomes particularly powerful in contemporary cities where public interaction is increasingly fragmented. Through temporary performance spaces, the project creates moments of collective gathering and shared experience.

Its architectural strategy is not focused solely on form-making. Instead, the project prioritizes interaction, accessibility, movement, and social participation.

The proposal demonstrates that architecture can function as cultural infrastructure without relying on monumentality or permanence. Through adaptability and openness, The Interfusion creates an alternative model for future urban cultural spaces.

Juror Commentary

Juror Bruno Rossi recognized the ingenuity of the proposal while also identifying its conceptual limitations:

“Ingenious solution, but it limits the number of art possibilities as its focus on a concert design.”

This observation introduces an important architectural discussion surrounding specialization versus adaptability within temporary performance structures. While The Interfusion primarily focuses on concert and performance-oriented configurations, its modular logic suggests the possibility for future expansion into broader artistic applications.

The commentary ultimately reinforces the strength of the proposal as a technically resolved and spatially compelling intervention while also encouraging further exploration of multifunctional cultural programming.

Rethinking the Future of Public Cultural Infrastructure

The Interfusion offers a compelling vision for the future of mobile performance architecture and temporary urban design. At a time when cities continue to negotiate the balance between regulation, accessibility, and public expression, the project demonstrates how architecture can operate as a bridge between institutional systems and everyday life.

Through its adaptable structure, deployable performance system, and socially driven architectural philosophy, the project transforms urban space into a platform for conversation, creativity, and participation.

More importantly, The Interfusion reminds us that architecture is not only about constructing buildings. It is also about shaping relationships between people, culture, and the city.

By reconnecting art with the street, the project reclaims public space as a place of collective imagination, proving that temporary architecture can generate lasting cultural impact.
