Sudameris Plaza: A Green Landmark Redefining the Skyline of Asunción

Sudameris Plaza, designed by the renowned British architecture studio Foster + Partners, is set to become the tallest building in Paraguay and a defining element of Asunción’s future skyline. Rising to 188 meters with 39 floors, this project is more than just a skyscraper — it’s a dynamic blend of institutional power, public engagement, and green innovation. Planned as the new headquarters for Sudameris Bank, the tower also incorporates commercial office space and public retail, creating a vertical campus embedded in nature.

Set to surpass the current tallest structure in the country, the 142-meter Icono Tower, Sudameris Plaza aims to create an “elegant” landmark in the heart of the capital. With its sculptural concrete frames, sky gardens, shaded plazas, and nature-integrated terraces, this project represents a thoughtful approach to vertical urbanism. Foster + Partners envisions the building as a modern urban oasis, where corporate architecture can coexist with public life and ecological sensitivity.

Design Concept and Spatial Composition

The overall design is defined by a series of prominent concrete frames that wrap the building’s glass core. These frames rise from the landscaped plaza, bending inward at the base and expanding slightly as they crown the tower. This bold gesture provides both visual rhythm and structural definition, while housing sky gardens that bring vegetation up the full height of the building.

The base of the tower includes a transparent glass retail podium and a public plaza with cafes, seating, and soft landscaping. This integration blurs the boundary between the tower and the city, fostering street-level activity and public accessibility. A double-height, set-back lobby marks the main entrance, accessed through lush gardens that buffer the building from the street.

Program Distribution and Vertical Zoning

Sudameris Plaza organizes its program vertically to reflect its multiple functions. The first six floors and the top two are designated for Sudameris Bank’s headquarters, offering open-plan offices, executive boardrooms, and exclusive gallery spaces. The mid-section of the building will provide flexible commercial office space for other tenants, with generous ceiling heights and access to outdoor terraces.

Open-plan work areas will face north, taking advantage of optimal daylighting, while collaborative zones on the southern side will offer views of the landscaped gardens and public spaces below. Double- and triple-height floors accommodate dynamic working environments and access to exterior terraces, providing breakout zones that connect indoor activity with fresh air and greenery.

Material Strategy and Structural Expression

The architecture of the tower relies heavily on expressive concrete, which is used both structurally and visually. The large-scale frames provide lateral support, creating wide column-free interiors, while visually referencing a monumental grid. These elements also host vertical greenery, aligning structural articulation with biophilic design goals.

Glazed curtain walls fill the voids between concrete frames, enhancing natural light penetration while allowing transparency across multiple levels. Terraces embedded within the structure enable layered interactions with the exterior environment, creating a more humane and livable skyscraper typology.

Architectural Analysis

Sudameris Plaza demonstrates a careful balance between monumental form and environmental performance. The expressed concrete skeleton isn’t merely decorative — it’s a structural and ecological device. It creates a rhythm that defines the building’s identity while supporting vertical gardens and integrating outdoor terraces that enhance workplace wellbeing.

The base-level gardens and public plaza contribute to a softened urban threshold, allowing the building to breathe and engage the pedestrian scale. The vertical zoning strategy reinforces a clear hierarchy of space, from public to corporate, without compromising openness. By interspersing greenery throughout the building, the design bridges ecological intention and spatial quality.

Instead of relying on generic glass-box typologies, the architects developed a distinct language through concrete tectonics and vertical landscaping. The project represents a refined approach to high-rise design, where visibility, greenery, and workplace innovation align with civic ambition.

Project Importance

Sudameris Plaza is a significant contribution to architecture in South America. It redefines what a corporate tower can be by prioritizing environmental interaction and public engagement over formal isolation. The project is a lesson in how regional urban contexts can host globally informed architecture that remains locally meaningful.

It teaches architects to rethink tall buildings not only as containers of program, but also as systems of social interaction and ecological integration. In a time of climate crisis and urban densification, Sudameris Plaza presents a future-forward model for sustainable skyscraper design that values community access and environmental stewardship.

This building matters now because it reframes corporate architecture through the lens of civic responsibility and design generosity. It positions green architecture not as a luxury but as a fundamental part of city-making.

✦ ArchUp Editorial Insight

Sudameris Plaza impresses through its sculptural geometry, blending rigid concrete framing with lush sky gardens and generous public space. The rhythm of the concrete exoskeleton creates a visual language that distinguishes the tower from typical office buildings. However, one may question whether its bold form will adapt well over time to changing programmatic needs. Nonetheless, the project elevates Paraguay’s architectural ambition and introduces a skyscraper that seeks civic dialogue, environmental wellness, and symbolic gravity in equal measure.

Conclusion

Sudameris Plaza is more than the future headquarters of a major bank — it’s a vision for a new kind of high-rise architecture in South America. By combining expressive structure, public realm integration, and vertical greenery, Foster + Partners has created a building that both dominates and contributes to its urban context.

This project exemplifies how skyscrapers can move beyond symbols of capital to become inclusive, performative, and environmentally conscious landmarks. As Asunción grows, Sudameris Plaza will stand not only as the country’s tallest building but also as one of its most forward-thinking. For architects and designers, it offers a powerful reference for transforming the typology of the urban tower in tropical and emerging contexts.
