Annibale Rigotti graduated from the Accademia Albertina di Belle Arti in Turin in 1890. His interest for the architecture of the Expositions dates back to 1902, when he participated in the designs for the Esposizione di Arte Decorativa Moderna, in Turin, and 1906, when he earned the second prize in a competition to design a Palazzo delle Esposizioni for the Esposizione del Sempione in Milan. In 1907, he travelled to Siam (currently Thailand), where he collaborated with Italian architect Mario Tamagno and engineer Carlo Allegri to design the Ananta Samakhom Throne Hall. He returned to Italy in 1909. In 1923 he went to Bangkok again, staying till 1926. He designed Villa Norasingh and the gardens of Saranrom Palace, and served as the chief architect for the Public Works Department. After returning to Turin, he designed with his son Giorgio Rigotti the Palazzo a Vela in 1961. Rigotti held several teaching positions, including Professor of Industrial drawing at the Istituto Tecnico G. Sommeiller (1893-1923). He also taught at the Politecnico of Turin, and at the Regia Scuola di Architettura di Torino from 1931-1933.
