THE ARC – A Coastal Architecture Vision for Rio de Janeiro
A transformative coastal architecture landmark that merges culture, movement, and communication, reconnecting Rio with its shoreline and its people.
The Arc is an ambitious coastal architecture proposal that redefines how Rio de Janeiro interacts with its waterfront. Conceived by Zeynep Uz and Cihan Polat, the project transforms the city’s iconic shoreline into a dynamic cultural interface where urban life, the sea, and public engagement converge. The design interprets the pier not merely as an extension into the water, but as a communicative landscape—one that bridges people, spaces, and experiences.
Set against the rhythmic backdrop of Rio’s soundscape, The Arc explores how architecture can act as both a medium of collective expression and a catalyst for social connection. By rethinking the pier typology through the lens of coastal architecture, the project proposes a new spatial paradigm that is fluid, interactive, and deeply rooted in the cultural energy of the city.
Reimagining the Pier Through Coastal Architecture
The defining geometry of the project—the sweeping arc—emerges directly from its coastal condition. Rather than projecting linearly into the sea, the design curves gently along the water’s edge, creating a continuous gesture that frames panoramic views of the city, the ocean, and the opposite shore. This curvature invites movement, guiding visitors through a spatial narrative shaped by changing perspectives, shifting light, and rhythmic structural repetitions.
This approach positions The Arc within contemporary discussions of coastal architecture, where resilience, adaptability, and sensory experience form the core of design thinking. The pier becomes both a promenade and a platform—a place to observe, gather, celebrate, and reflect.
A New Athenaeum for the City of Sounds
Embedded within the pier system is a reinterpretation of the athenaeum—a space dedicated to learning, cultural production, and the exchange of knowledge. Here, the athenaeum becomes an architectural narrative about communication itself. It is not confined by walls, but instead unfolds as an open-air environment shaped by the city's climate, topography, and acoustic identity.
Rio’s reputation as the "city of sounds" plays a central role in the project’s conceptual framework. The designers explore how an athenaeum could operate in a city where music, waves, and human activity form a continuous, intertwined composition. Through semi-open shells and tensile structures, the project creates acoustically engaging pockets where people can gather, perform, learn, or simply listen.
Architecture as a Medium of Communication
The project proposes that architecture in our technological era is no longer static. It is a dynamic form of communication—one that adapts, responds, and evolves. The Arc emphasizes that spaces for learning and gathering must reflect the fluid nature of modern knowledge exchange. As digital formats reshape how information is shared, physical spaces must provide environments that support sensory experience, embodied interaction, and communal presence.
The pier therefore becomes more than a destination; it becomes a spatial communicator. Its structural rhythm, material transitions, and shifting elevations create a landscape that invites interpretation and dialogue between visitors and the environment.
Structural Expression and Spatial Storytelling
The Arc is composed of a striking array of vertical elements—pillars rising from the water like rhythmic markers. These verticals serve as structural anchors for cable-supported walkways, creating an interplay of tensile and compressive forces. Their alignment and spacing evoke both musical rhythm and maritime infrastructure, grounding the project in its coastal identity.
The elevated walkways offer sequences of framed views:
- the expanse of Guanabara Bay,
- the sweeping city skyline,
- the undulating roof forms of the cultural pavilions,
- and the horizon where water meets sky.
These transitions create an experiential promenade where visitors navigate not just physical space, but layers of meaning embedded in form and structure.
The Pavilion Forms: Organic Movement and Collective Shelter
At the heart of The Arc lies a cluster of organically curved pavilions. Their shell-like forms echo marine life and the fluid motion of waves. These structures serve as amphitheaters, shaded gathering zones, and cultural event spaces. They embody the spirit of an open athenaeum—flexible, transparent, and adaptable to changing public needs.
Through their lightweight spans and porous construction, the pavilions craft environments where sound resonates naturally and people gravitate instinctively. They become social anchors within the extended pier system.
Coastal Connectivity and Human Experience
The entire project is designed around a simple yet profound idea: people come together through movement and shared horizon lines. By extending access deep into the bay, The Arc creates new vantage points from which to experience Rio—a city known for its dramatic topography and vibrant culture.
The pier becomes an elevated stage for everyday life, allowing residents and visitors to:
- walk intimately alongside the water,
- witness sunrise and sunset unobstructed,
- gather in communal plazas,
- and participate in events that transform the waterfront into a civic theater.
This emphasis on human experience makes The Arc not just a piece of infrastructure, but a cultural landscape that reinforces community relationships.
Technology, Learning, and the Future of Public Space
The designers propose that evolving modes of communication should inform the design of public architecture. As learning becomes multidimensional—combining digital, auditory, spatial, and social inputs—spaces like The Arc must support hybrid forms of engagement.
The project thus becomes a prototype for future coastal architecture that embraces:
- digital learning environments,
- open-air cultural programming,
- community-driven communication,
- adaptation to climate conditions,
- and flexible public use.
It is architecture as future‑proofed infrastructure.
A New Icon for Rio’s Waterfront
The Arc stands as a bold vision for how coastal architecture can reshape urban life. It reconnects Rio with its shoreline through a language of curvature, rhythm, and light. It invites people to walk, learn, communicate, and celebrate in a dynamic spatial environment shaped by the sea.
By blending cultural programming with structural expression, Zeynep Uz and Cihan Polat offer Rio not just a pier, but a transformative architectural experience—one that captures the spirit of the city and sets a new benchmark for waterfront design.
