Like his father he was an architect active during the Baroque period. Bagnato is mostly remembered for his works in the service of the Teutonic Knights and the Prince-Bishop of Constance.
From 1759 onwards, he worked for Prince-Bishop Franz Konrad von Rodt of the Bishopric of Constance, finishing amongst others the New Castle and the chapel of the seminary in Meersburg.
