In 1945, the Japanese launched a coup against the French. To avoid the dangers of war, the Governor-General of Indochina issued a decision to move the School of Architecture from Hanoi to Da Lat. Due to the unstable political situation at the time, the school had to suspend operations for a period. On February 1, 1947, the school resumed its activities under the name Da Lat School of Architecture. On March 8, 1948, the school was recognized by the French Government’s Inter-ministerial body as one of the regional schools of architecture and a branch of the École Nationale Supérieure des Beaux-Arts in Paris.
By the end of 1948, the Da Lat School of Architecture was incorporated into the University of Indochina and upgraded to the College of Architecture. According to an announcement by the French Government on September 6, 1948, the Da Lat School of Architecture was no longer a branch of the École Nationale Supérieure des Beaux-Arts in Paris. In 1950, following the cultural treaties signed on December 30, 1949, and May 30, 1950, between Vietnam and France, the University of Indochina was renamed the University of Hanoi. The Da Lat College of Architecture fell under the jurisdiction of the University of Hanoi.
At the end of 1950, the Da Lat College of Architecture was relocated to Saigon, situated at 196 Pasteur, Saigon, and renamed the Saigon College of Architecture.
Following the Geneva Accords, the University of Hanoi became the National University of Vietnam, while the University of Saigon was established in the South. The Saigon College of Architecture was under the jurisdiction of the University of Saigon.
In 1967, according to Decree No. 159/SL/QD of the Government of the Republic of Vietnam signed on October 30, 1967, the Saigon College of Architecture was upgraded to the University of Architecture Saigon, under the University of Saigon.
