Additionally to his built projects, Loos is noted for his essay/manifesto "Ornament and Crime" written in 1908. In that he expressed a idea that a progress of culture is associated using a deletiin of ornamentation from either everyday objects, & that it was a crime to inflict craftsmen or even builders to waste their period on ornamentation that served to hasten the period while an object was obsolete. Accordingly, a virtually all primitive societies use a great deal of decoration & a virtually all advanced societies have there are there are no superfluous ornamentation, or even at least there exists advantage inside suppressing ornamentation which serves no utile purpose. In the equivalent essay Closet asserted that "All art is erotic," & that the European huhuman world health organization tattoos himself is either the crook or even the pervert; whenever the tattooed man dies away from prison, Water closet reasoned, these are sole because he did non survive hanker plenty to commit his inevitable execution.

This essay occurs as repudiation of the function of the Vienna Secession, the Austrian version of Art Nouveau. Closet' provocative catch-sentence was taken higher per Modern Movement in architecture, the more illustrious catch-sentence of which is "form follows function". Ironically, in the years between 1893 and 1896 Loos lived and worked within United States, at one point holding a position in the professional of Louis Sullivan (according to Robert Hughes's "Shock of the New").

Loos is likewise known for his infamous entry to the 1922 Chicago Tribune competition, which took the form of one prodigious Doric column.
