A mason by education, Fuchs studied with Jan Kotěra at the Academy of Fine Arts in Prague between 1916-1919, and then later worked in Kotěra's atelier for two years. After 1922, Fuchs resided in Brno, where he first worked at the city construction office and then later (from 1929) in his own atelier. Between 1947-1958, Fuchs was a professor of architecture at Brno University of Technology. He participated in several professional associations abroad (e. g. British RIBA). His projects, realized mainly in Brno, were predominantly influenced by functionalism.
