What was the purpose of Le Corbusier’s Pavilion of the New Spirit in Paris?

The Pavilion of the New Spirit (Pavillon de l'Esprit Nouveau), designed by Le Corbusier for the 1925 Paris Exposition, served as a physical manifestation of his architectural and urban planning theories.1

The pavilion was intended to promote his vision of a modern, industrialized society, functioning as a practical demonstration of his belief that a house should be a "machine for living in". It showcased his commitment to Functionalism and the use of standardized building components and mass production to address the social problems of housing. By presenting these concepts, the pavilion acted as a "footnote" to his broader, ambitious dream of creating a new, rationalized city characterized by efficient urban patterns and standardized, functional living spaces.21
