“Dan Graham’s unrealized project “Alteration to a Suburban House” (1978), generates a hallucinatory, almost Expressionist image by means of a historical critique of conceptual art. In this work, conceptualism is the discourse which fuses together three of the most resonant architectural tropes of this century (the glass skyscraper, the glass house and the suburban tract house) into a monumental expression of apocalypse and historical trajedy.” – Jeff Wall.
