[8] Growing up in the shadow of a strong Tuscan tradition, he became one of the most prominent representatives of the Art Nouveau style, occasionally incorporating his personal taste influenced by Renaissance classical architecture.
One of his earliest known projects was the construction of the Church of San Martino in Freddana in Pescaglia, in the province of Lucca, built between 1897 and 1904 in a lively eclectic style.
[9][10] In Lucca, he designed the Brancoli Tower, a monumental cross-monument built in 1900, over 18 meters high, inaugurated on 13 October 1901 (later destroyed by retreating German troops during World War II in July 1944 and subsequently restored).
[17][18] Orzali also designed major urban transformations that extended from the lower part of the street, which opens onto the area in front of Genova Brignole station and the Bisagno River, reaching Corso Italia and Molo Giano.
[21] "thanks to the initiative of an esteemed professional from Genoa, the architect Gaetano Orzali, [is in progress] a study precisely aimed at the urban development of the city in the lower Bisagno valley and its expansion towards the sea, along the entire beach and the adjacent aquatic area between Molo Giano and Punta del Vagno"In Genoa, Orzali was also the designer of many elegant residential architectures, such as the famous Villa Lavarello on Via San Nazzaro in the city of San Francesco d'Albaro,[22] Villa de Nobili Fossati Raggio (1906, modified in 1919),[23] the Palazzo at the corner of Via G. Carducci and Via G. Medici del Vascello in Albaro, the Palazzo on Via Alessandro Malaspina in Cornigliano, and several significant villas on Via San Nazaro in Albaro.
[30] In 1910, he decided to become a life member of the Touring Club Italiano, paying the considerable amount of one hundred lire, a significant sum for that time.
[43][44] In Viareggio, the area where his father Modesto also worked, some of his notable projects include the Chizzolini Villas (1910),[45] Hotel Imperiale (1913),[46] and Villino Il Guscio.
