Banco Sul Americano Building, Modernist skyscraper in Bela Vista District, Brazil.

The Banco Sul Americano Building is a modernist skyscraper standing at the intersection of Avenida Paulista and Rua Frei Caneca, with 17 stories of concrete construction. The structure serves commercial purposes across its floors in São Paulo's financial center.

Rino Levi Arquitetos Associados built the Banco Sul Americano between 1961 and 1963, drawing on Gordon Bunshaft's Lever House of 1952 in New York. The trapezoidal 2,660 m² corner plot held a bank base with two entrances and a 13,345 m² office tower. In 1966 the Banco Sul-Americano merged with Itaú, forming the Banco Federal Itaú Sul-Americano.

The gardens at the main front and the entrance on the side wall were planned by Roberto Burle Marx, who worked with Rino Levi on many projects. Widening Avenida Paulista erased most of the front garden. Levi died in 1965 during a botanical expedition in Bahia with Burle Marx.

The building is accessible from the sidewalk along Avenida Paulista or Rua Frei Caneca, and its corner location makes it easy to spot. Since it operates as an active commercial building, public interior access is limited, but the exterior facade can be viewed from the streets.

The building's climate control relies on passive design rather than air conditioning: the Instituto de Pesquisas Tecnológicas rates it the most energy-efficient building on Avenida Paulista, even when sun strikes the main facade directly. Burle Marx's original front gardens were largely lost when the avenue was widened.
