On May 25, 1935, the cornerstone was laid on the Centennial (now Figueroa Alcorta) and Río de la Plata (Udaondo) Avenues. On December 1 of that year, the Steering Committee presented the approved project in detail to its members at an assembly. They obtained a loan of $2,500,000 from the government and on September 27, 1936, construction began under the direction of architects José Aslan and Héctor Ezcurra.
