[3] Before she finished her schooling in 1948, Suárez began working under the direction of Antonio Bonet Castellana and Jorge Ferrari Hardoy [es] on the team studying the city plan for Buenos Aires.

She graduated in 1950 with the Gold Medal for her class and continued her studies, traveling to England on a postgraduate fellowship offered by the British Council.

[2] In 1952 she went to Mexico City to write about the Eighth Pan-American Congress of Architects for Revista de Arquitectura and met Frank Lloyd Wright.

[3] She became the first woman to hold a chair in the Faculty of Architecture, Design and Urbanism (es) (FAU-UBA) at the University of Buenos Aires in 1957 and began her teaching activities at that time.

That same year, Suárez-Sarrailh won the competition for their design of the Regulatory Plan of Mar del Plata[3] and directed a proposal for the neighborhood Casa Amarilla, which integrated among the 15,000 homes pedestrian and vehicular districts to create both a functional and visual cohesion.

Winning an Organization of American States (OAS) scholarship in 1964, Suárez returned to Europe and studied regional planning in Great Britain and Scandinavia.

[10] In 1969 she won the design competition for building the civic center of Colonia Catriel in Río Negro Province, with her proposal which incorporated the use of environmental elements such as curtains of trees, ditches and mirrors of water to add interest to the bare and inhospitable appearance of the Patagonian Desert.

Though she maintained her home in Recoleta, Buenos Aires, Suárez also kept a residence in Punta del Este, Uruguay during the military junta.
