The Brazilian Embassy was designed in 1976 by Rio native Olavo Redig do Campos. The official inauguration was in 1989, and it is the headquarters of the chancellery of the Brazilian Embassy.

One of the main features of the building are the seven levels of balconies. They simulate huge pots, from which foliage stands out that changes throughout the year, more or less dense, depending on the season. It is the only work of the architect who headed the "Heritage Conservation Service of the Ministry of Foreign Affairs" for 30 years. For this reason, he designed this building, in addition to the one in Washington (United States), and diplomatic residences in Beirut (Lebanon) and Dakar (Senegal). The building is located in the Retiro neighborhood, dominated by buildings such as the French Embassy, the Pereda Palace, and all the works that make up the APH 30 Avenida Alvear, between Callao and Libertad. In fact, a survey revealed the Clorindo Testa National Library as the ugliest building in the City. The facade of the embassy is made of hammered concrete. It captures the language of Brazilian architecture from the 1960s and 1970s in the embassy. "I always say that beyond personal tastes, architecture represents an aesthetic period," says Magal Marazzo, who was in charge of the Mar del Plata house museum during its restoration. The embassy was designed by César Pelli, a pioneer in the field of international architecture. It is located in the center of the city of Brasilia, in the heart of the capital city of Buenos Aires, on the banks of the Arroyo de la Plata. The building is currently home to the Brazilian Institute of Architects, which was set up by Oscar Niemeyer in the 1960s and 1970s to promote Brazilian architecture in the world. The Institute is based in the same building as the U.S. Embassy in Brasilia and is run by the Institute of Architecture and Design, which is based at the University of the South of Brazil.
