Edificio República, Modern office building in San Nicolás district, Buenos Aires, Argentina.

Edificio República is an office tower on a narrow triangular block where Avenida Eduardo Madero meets Bouchard street, in San Nicolás. Its long convex front faces east over the Río de la Plata, clad in white aluminium panels and varied glass, with metal bars tracing the curve. The main entrance sits on a five-storey cylindrical volume at Tucumán and Bouchard, facing Plaza Roma, and the main body wraps around it in a concave line.

The building was constructed between 1994 and 1996 and represented a turning point for intelligent office towers in the city. Renowned architect César Pelli shaped its design with a contemporary vision.

The structure manifests the International Style architecture principles through its geometric forms, materials, and integration with the surrounding urban environment.

The main entrance is at the corner of Tucumán and Bouchard, facing Plaza Roma, inside a five-storey cylindrical volume. The building has three basement parking levels, a ground floor with a conference room, a mezzanine and 20 office floors; the 21st level holds a terrace with a heliport and the 22nd the machine room.

The public plaza at the triangular corner of Tucumán street was designed by the landscape firm Balmori Associates. Raised above sidewalk level, its shape recalls the deck of a ship, a nod to nearby Puerto Madero. A branch of Le Pain Quotidien now occupies the hall section facing the plaza.
