She is among a small group of women architects who were working in Asia during her career. While some sources credit her as the first woman architect in Asia, and women like
Perin Jamsetjee Mistri and
Dora Gad preceded her by a decade or more. After working for a short time in United States, she returned to India in 1951 and became a member of a team headed by
Le Corbusier for planning the design and construction of Chandigarh during 1951–63 and 1968–70. She was the only connection between Le Corbusier,
Pierre Jeanneret, and the Indian architects and administrators. Her assignments included the Home Science College, the Women's Polytechnic and many residential complexes of the ministers. Her third assignment, from 1971 to 1976, was as the Chief Architect, who she worked for the second stage of Chandigarh city planning. Chowdhury's assignment during the period 1963–65 was as the Director of the School of Architecture of Delhi. During this period she also authored a book of memories of Le Corbusier titled
Those Were The Days. Chowdhury's work, like that of the architects she worked with, was deeply impacted by the climate and the limited footprint. Chowdhury also designed furniture and adapted Jeanneret's furniture to a smaller scale. This was possibly inspired by her own petite stature. ==Later life==
