He was educated at the Albertina Academy of Fine Arts in Turin, where he became an instructor after graduating in 1895. He travelled to Siam in 1900, where he entered employment with the Siamese government in a twenty-five-year contract. He was among many Westerners, particularly Italians, who were employed as architects and civil engineers during the reign of King Chulalongkorn. He produced many works, and contributed extensively with Annibale Rigotti, most notably on the Ananta Samakhom Throne Hall.
He married his classmate of Accademia Albertina, Marianna Zuccaro, who came to Bangkok in 1901.
After the term of his government contract (1900-1925), he was asked by the Siamese government to continue his work for Villa Norasing (today House of Government) during its last phase of construction, in May 1926 he returned to his homeland with a lifetime retirement income from the Government of Siam.
