centrally placed Room A, featuring a model of a mid-rise housing development for Evanston, Illinois, by Chicago architect brothers Monroe Bengt Bowman and Irving Bowman, as well as a model and photos of Walter Gropius's Bauhaus building in Dessau. In the largest exhibition space, Room C, were works by Le Corbusier, Ludwig Mies van der Rohe, J. J. P. Oud and Frank Lloyd Wright (including a project for a house on the Mesa in Denver, 1932). Room B was a section titled "Housing", presenting "the need for a new domestic environment" as it had been identified by historian and critic Lewis Mumford. In Room D were works by Raymond Hood (including "Apartment Tower in the Country" and the McGraw-Hill Building) and Richard Neutra. In Room E was a section titled "The extent of modern architecture", added at the last minute, which included the works of thirty seven modern architects from fifteen countries who were said to be influenced by the works of Europeans of the 1920s. Among these works was shown Alvar Aalto's Turun Sanomat newspaper offices building in Turku, Finland.

Barr hired architectural historian and critic Henry-Russell Hitchcock and Philip Johnson to curate the museum's first architectural exhibition. The three of them toured Europe together in 1929. The three of them also discussed Hitchcock's book about modern art. By December 1930, the first written proposal for an exhibition of the "new architecture" was set down, yet the first draft of the book was not complete until some months later. Publications The 1932 exhibition led to two publications by Hitchcock and Johnson: The exhibition catalog, "Modern Architecture: International Exhibition" The book, The International Style: Architecture Since 1922, published by W. W. Norton & Co. in 1932. reprinted in 1997 by W. W. Norton & Company Previous to the 1932 exhibition and book, Hitchcock had concerned himself with the themes of modern architecture in his 1929 book Modern Architecture: Romanticism and Reintegration. According to Terence Riley: "Ironically the (exhibition) catalogue, and to some extent, the book The International Style, published at the same time of the exhibition, have supplanted the actual historical event."
