 For Hundertwasser, human misery was a result of the rational, sterile, monotonous architecture, built following the tradition of the Austrian architect Adolf Loos, author of the modernist manifesto "Ornament and crime" (1908).He called for a boycott of this type of architecture, and demanded instead creative freedom of building, and the right to create individual structures.In 1972 he published the manifesto "Your window right — your tree duty".
