He produced the plans for the Colonne de la grande Armée at Wimille, erected in 1804 on the order of Napoléon I. From 1825 to 1827, he built Boulogne-sur-Mer's second-ever theatre, which was destroyed in a fire in 1854.
He was charged with completing the Palais Brongniart between 1813 and 1826, after the death of Alexandre Théodore Brongniart.
