Torre BankBoston, Office tower in Retiro district, Buenos Aires, Argentina

Torre BankBoston is a modern office tower in Buenos Aires's financial district rising 33 floors and 137 meters high. The building features dual glass facades oriented toward the city and the river, creating distinct visual profiles depending on your vantage point.

Designed by César Pelli with Mario Roberto Álvarez y Asociados as local associate, the tower was inaugurated in 2001 in the presence of President Fernando de la Rúa. It was Pelli's second work in Buenos Aires, after the Edificio República. On 30 June 2005 the lobby gained Guillermo Roux's mural "Homenaje a Buenos Aires"; the corporate interiors were by Hampton-Rivoira.

The lobby holds Guillermo Roux's mural 'Homenaje a Buenos Aires', inaugurated on 30 June 2005. The corporate interiors were designed by the Hampton-Rivoira studio, which also restored the old Banco de Boston branch.

The tower stands in Catalinas Norte, a district of separated prism-shaped buildings outside the traditional street grid, close to the river, the micro-centro and Puerto Madero. Its two main fronts face Avenida Leandro N. Alem toward the city and Avenida Madero toward the river. The air-intake balcony on the 16th floor, at the first setback of the south facade, draws air away from traffic pollution.

The crown of the tower is cut so that each face ends in a different profile, and its glass is a different colour from the rest of the facade. The curtain wall uses anodised aluminium mullions shaped as half-rounds in varying sections, horizontal and vertical, so the tower's image shifts with the light.
