Foster + Partners Designs High-Rise Office Tower for Sudameris Bank in Asunción, Paraguay

Foster + Partners has won an international competition to design the headquarters of Sudameris Bank in Asunción, Paraguay. The project, named Sudameris Plaza, is a 39-storey office tower featuring an exposed concrete frame and an angular form. It includes a landscaped plaza, art gallery, auditorium, and a large public garden at the tower's base. The studio aims to integrate greenery throughout the shared spaces of the building, fostering a strong connection with nature from within the tower.

Sudameris Plaza is a 188-meter-tall office building that includes cafés, shops, and social spaces, which Foster + Partners envisions as being fully immersed in nature. The tower is set back from the street, creating a covered walkway around its base that leads to a public garden. This ground level is expected to be lined with commercial, service, and cultural spaces open to the public. The proposal also includes preserving or relocating the site's existing trees to a nearby plaza, enhancing the green character of the building's environment.

David Summerfield, Head of Studio, said: "The greenery travels up the building through sky gardens, improving wellbeing by offering varied breakout spaces with nature." The interior design features open-plan workspaces with double- and triple-height volumes, occupying 12-meter-deep floorplates on the building's north side. These areas are linked to outdoor green terraces, while collaboration zones on the south side overlook the new public garden.

Sudameris will occupy the first six floors and the top two levels of the tower, while the intervening floors will be leased as commercial office space. Each floor comprises 1,200 square metres and the top levels will include private offices, a boardroom, and a private gallery. Sudameris offices will offer panoramic views of Asunción from expansive terraces. A double-height lobby, serving both employees and visitors, will be an important element of the interior design.
