Postmodernism in architecture emerged in response to Modernism, with Robert Venturi criticizing Modernism's "puritanical moral language" and preference for simplicity and rationality. Venturi proposed alternatives like "both-and" instead of "either-or" and "decorated sheds" over "duck." Examples of Postmodern architecture include the works of Australian architects Glenn Murcutt, who incorporated natural elements into his designs, and Harry Seidler, known for blending international styles with a focus on human scale.
