For the architecture theorist Charles Jencks, Frank Gehry’s Guggenheim Museum in Bilbao, Peter Eisenman’s Aronoff Center in Cincinnati, and Daniel Libeskind’s Jewish Museum in Berlin are architectural replies to the question of the cultural outgrowths of ‘complexity science’. In the light of new technologies being used in architecture, it seems necessary to explore Jencks’s position from new perspectives and to ask: in the context of architectural production, is it possible to discuss complexity not only as an artistic-aesthetic category, but also as a fundamental technical-constructive idea? Contemporary information technologies confront architectural-theoretical discourses with developments that call for an expanded theoretical instrumentarium. It remains unclear which architectural language might be used best to approach the concept of complexity associated with information technologies.
