Cubism was relevant to an architecture seeking a style that needed not refer to the past. Thus, what had become a revolution in both painting and sculpture was applied as part of "a profound reorientation towards a changed world". The Cubo-Futurist ideas of Filippo Tommaso Marinetti influenced attitudes in avant-garde architecture. The influential De Stijl movement embraced the aesthetic principles of Neo-plasticism developed by Piet Mondrian under the influence of Cubism in Paris. De Stijl was also linked by Gino Severini to Cubist theory through the writings of Albert Gleizes. However, the linking of basic geometric forms with inherent beauty and ease of industrial applicationwhich had been prefigured by Marcel Duchamp from 1914was left to the founders of Purism, Amedee Ozenfant and Charles-Edouard Jeanneret (better known as Le Corbusier,) who exhibited paintings together in Paris and published Apres le cubisme in 1918. Le Corbusier's ambition had been to translate the properties of his own style of Cubism to architecture. Between 1918 and 1922, Le Corbusier concentrated his efforts on Purist theory and painting. In 1922, Le Corbusier and his cousin Jeanneret opened a studio in Paris at 35 rue de Sevres. His theoretical studies soon advanced into many different architectural projects.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What years did Le Corbusier not concentrate his efforts?
