In the 1930s, Le Corbusier expanded and reformulated his ideas on urbanism, eventually publishing them in "La Ville radieuse" (The Radiant City) in 1935. Perhaps the most significant difference between the Contemporary City and the Radiant City is that the latter abandoned the class-based stratification of the former; housing was now assigned according to family size, not economic position. Some have read dark overtones into "The Radiant City": from the "astonishingly beautiful assemblage of buildings" that was Stockholm, for example, Le Corbusier saw only "frightening chaos and saddening monotony." He dreamed of "cleaning and purging" the city, bringing "a calm and powerful architecture"—referring to steel, plate glass, and reinforced concrete. Although Le Corbusier's designs for Stockholm did not succeed, later architects took his ideas and partly "destroyed" the city with them.
