He studied in the office of New Orleans architect George Purves early in his career. Freret went on to study architecture at the École des Beaux-Arts in the early 1860s in the atelier of Charles-Auguste Questel, one of the first Americans to study at the Ecole. He returned to the United States due to the Civil War, joining the Confederate Army's engineering corps. He was wounded in the Siege of Port Hudson, and in 1865 returned to New Orleans to open his own architecture practice.
