All important architecture of the last century was strongly influenced by political systems. Look at the Soviet system, with its constructivism and Stalinism, Weimer with its Modern style, Mussolini and, of course, the Nazis and Albert Speer's colossal structures. Today's architecture is subservient to the market and its terms. The market has supplanted ideology. Architecture has turned into a spectacle. It has to package itself and no longer has significance as anything but a landmark.
Rem KoolhaasThere's something really interesting about current urbanism: the only model is the universal model, and there is increasingly incapacity to consider the virtues and the qualities that are there, and then to build on them. The only thing is complete transformation.
Rem KoolhaasAny architectural project we do takes at least four or five years, so increasingly there is a discrepancy between the acceleration of culture and the continuing slowness of architecture.
