The Teniente General Castiñeiras building stands on a triangular plot of land in the heart of Buenos Aires, one of the most emblematic of the city's modern architecture. Better known as the SOMISA Building, its origin was the result of a design competition for the design of the new headquarters of the Sociedad Mixta Siderúrgica Argentina company. The first prize was won by MRA+A, Mario Roberto Álvarez & Associates, and its construction began around 1966, with the works completed in 1977.
Located in the Retiro district of the Autonomous City of Buenos Aires is the IBM building designed by Mario Roberto Álvarez & Associates. Conceived to house the headquarters of the IBM company, this office building was designed around 1979 and consists of a tower supported by two large concrete structural cores on a base, which is separated from the ground and the shaft of the tower to house the ground floor and a level of common areas in order to maintain the urban scale. The language of the building is recognizable from a distance as it is formed by an enclosure of horizontal bands of glass and exposed concrete parapets-parasols, which achieve a dialogue and balance in the proportion of full and empty spaces.
