Starting in the 1920s, the new architectural style prevalent on campus became Neo Gothic. The complex formed Howard, Morrissey, and Lyons Halls, was designed in gothic architecture by Vincent Fagan and Francis Kervick, who were also professors of architecture at the university. These three buildings was constructed out in the usual yellow brick and a minimum of stone, in order to make them mesh better with the previous buildings and their surroundings. In line with the Gothic style, they feature pointed arches, spires, slate roofs, gables, and projecting bay of stone. Yet, they retain some elements of the French vernacular and Victorian Gothic of the previous buildings on Main Quad. They also were influenced by Tudor Gothic style. A second wave of buildings was built in the 1930s by the Boston-based firm of Maginnis & Walsh. Alumni and Dillon Hall were built in 1931. Compared with the buildings by Fagan and Kervick, the gothic style was closer to the Collegiate Gothic, with stone carvings and high gable roofs, and lacked those French vernacular elements that tied Howard, Morrissey, and Lyons to the Main Quad architecture. Maginnis and Walsh also built Zahm and Cavanaugh in the 1936–37, in a similar style but lacking the ornate exteriors and statuary of Alumni and Dillon. Breen-Phillips and Farley followed in similar style in 1939 and 1947.
