On November 26, 1936, Mayor Mariano de Vedia and Mitre provided for the construction of a building to house the Teatro del Pueblo, and on December 23, a theater located on 1530 Corrientes Avenue was expropriated for the purpose.

The Italian-style stage is equipped with a mouth of variable sizes (between 11 and 16 meters) and has a center section that can move vertically, in whole or in part, through nine lifts operating simultaneously or separately.

The ceiling of the Martín Coronado is decorated with a colored cement relief (4 by 2.50 meters) entitled Allegory to the Theater and completed in 1962 by local sculptor José Fioravanti.

The salon is named for Juan José de los Santos Casacuberta, the preeminent performer of the nineteenth century Argentine stage, and perhaps the first classically trained actor in local dramatic history.

The lobby of this salon is graced by a mural (35 by 11 meters) by Luis Seoane, titled The Birth of the Argentine Theater, and completed in 1960, as well as allegorical terracotta reliefs by sculptor Carlos de la Cárcova and a steel sculpture (Continuity) by Enio Iommi.
