Mollino designed a number of buildings in Turin, including the Faculty of Architecture at the
Politecnico di Torino. He produced working drawings for the doors and windows of most of his buildings. Mollino understood architecture as a form of expressive language rather than a purely academic field. He frequently combined traditional building knowledge with experimental structures, drawing inspiration from Alpine building traditions. He was drawn to complexity rather than simplicity. This direct contact with
Expressionism had a lasting impact on his work, visible in the first building he completed, the Sede Federazione Agricoltori () in
Cuneo (1933–35). In 1933, Mollino published a multi-part short story entitled
Vita di Oberon () in the architectural journal
Casabella. Written as prose fiction, it served as a personal manifesto of his architectural approach. With this manifesto, which bears traces of
Futurism from a youthful infatuation, Mollino began a creative journey in which he would consistently combine the roles of architect and storyteller. In 1934, Mollino began to explore
Surrealism, a movement that remained a constant source of fascination throughout his life. In August, he published his second short story, ''L'amante del duca'' (, 1934–36), a dreamlike fiction whose protagonist is the imaginary architect Faust. The Società Ippica Torinese (, 1937–40) is Mollino's first masterpiece and his first opportunity to give shape to a modern surrealist architecture that extended his interior designs and furniture of the 1930s, aiming to "move the concepts of surreal interior space towards an intransigently functional unity".
Wartime theory In 1941, Mollino published an article about the Turinese architect-engineer
Alessandro Antonelli, made famous by his towering
Mole. The article reveals Mollino's growing interest in the "organic," understood not as a reference to
Frank Lloyd Wright but as the structures of animal and plant organisms as sources of inspiration for designs ranging from coat hangers to buildings. In those same years, Mollino theorised a new form of "synthetic eclecticism" based on treating architecture as a language. During this period, dominated by the
Second World War, Mollino wrote articles and books about art, architecture, photography, and skiing, always from the perspective of a practising designer.
Postwar buildings As the war ended, he put his ideas into practice by designing the most influential of his buildings, the Slittovia del Lago Nero (, 1946–1947). Its structure combines cutting-edge
Vierendeel trusses with a traditional interlocking log enclosure, creating an extraordinarily dynamic, three-dimensional building. Mollino called it a "flying chalet," inspired by the traditional
Walser alpine architecture he had studied in summer 1930, producing detailed analytical drawings. The Slittovia del Lago Nero is part of a group of projects, including the unbuilt Casa Capriata (1945) and the Casa del Sole (1945–54) in
Cervinia, inspired by traditional
vernacular architecture reworked in modernist terms. In 1945, together with the sculptor
Umberto Mastroianni, Mollino won a competition for a war memorial, completed in 1947, for the Monumental Cemetery on the outskirts of Turin. From 1949 until his death, Mollino taught at the Faculty of Architecture in Turin, becoming a full professor in 1953. In 1950, he won a competition to redesign the interior of Turin's
RAI Auditorium within an existing building. In 1952, he designed the Casa Cattaneo overlooking
Lake Maggiore; the two-story house is composed of a long, cantilevered beam supported at one end by two leg-shaped pillars, resembling an animal crouching on the lawn slope, ready to jump.
Later career The death of his father in December 1953 plunged Mollino into a personal crisis, leading him to abandon architecture for several years in favour of other pursuits. In 1955, he designed the DaMolNar, a car that competed that year in the
24 Hours of Le Mans. In 1956, he took up flying, specializing in
aerobatics, and later competed in Italian and European competitions. He also turned to
nude photography. In 1959, he returned to architecture, entering the competition for an exhibition pavilion in Turin marking the centenary of Italy's unification. From this point on, his large-scale urban buildings, which remain in use today, are characterised by reinforced concrete structures. These include the Camera di Commercio di Torino (, 1965–73) and the
Teatro Regio di Torino (, 1973). The Teatro Regio, an important part of the monumental
Piazza Castello, offers fantastic spaces in which Mollino translates
Piranesi's
Prisons into a brutalist, curved, labyrinthine space on four levels that constitute the foyer.
