Rafael Viñoly Architects has completed Vilo Tower, a 16-storey, 60-metre-tall office building in Buenos Aires, developed as the new headquarters for Corporación América. The project occupies a prominent site along Avenida del Libertador, one of the city’s most active urban arteries running parallel to the coastline, where transparency and structural clarity are deployed as defining architectural tools.

The building’s identity is driven by its fully glazed façade, composed of large-format translucent glass panels measuring 7.15 metres by 2.2 metres. These panels enable a sequence of double-height office floors along the main elevation, establishing a strong vertical rhythm while maximising daylight penetration. At the curved corners, the façade is executed without visible mullions, allowing the glass envelope to wrap continuously and visually blur the boundary between interior and exterior.

Structurally, Vilo Tower is conceived as a hybrid system, pairing a conventional concrete frame with a two-storey modular organisation. Structural engineering was delivered by Curutchet del Villar, enabling spatially varied floor plates that support flexible office layouts. Along the façade, double-height volumes are complemented by central mezzanine levels, which vary in width from floor to floor, while single-height spaces are positioned toward the rear of the building.

A defining architectural gesture is the exposed concrete scissor stair and elevator core, located on the building’s backside. This vertical spine contrasts with the lightness of the glazed frontage, openly expressing the building’s circulation and structural logic. Mechanical, electrical, and fire protection systems were engineered by GNBA, carefully integrated to support the building’s open volumes and façade transparency.

At ground level, the tower expands into a three-storey base envisioned as an “urban greenhouse”, with the lowest level set below street grade. A triple-height lobby accommodates a public restaurant, connected to the main elevator bay by a black-clad spiral staircase, while flared concrete columns support a landscaped green roof above. Interior spaces feature light wood finishes, dark-toned furniture, and textured ceiling and wall panels, complemented by architectural lighting designed by Cappiello + Partners.

Construction management was handled by Amarilla, coordinating execution of the hybrid concrete structure and large-scale glazed façade system. The top floor incorporates a terrace enclosed by the same double-height glass envelope, with its ceiling left open to the sky. The project is targeting LEED v4 Core and Shell Gold certification.
