The second concerns his open, flexible approach that accepts uncertainties and rejects dogmatism and the critique of the privileged role of style and composition in the modern architectural discourse.

Being inspired by the lesson of modernism, the curtain façades, detached from structure and enhanced by light, transparent or translucent screens of glass or metal seem to be a tribute to contemporary technologies, yet are not subservient to them.

"[6] According to Frederic Migayrou, "All of Dominique Perrault’s work questions the figural aspect of architecture, its ability to provide meaning, to build a dynamic image woven out of social and cultural values.

[…] Dominique Perrault weaves his position between rationalism that seeks to articulate laws for the composition of typological elements, and a structuralist understanding of architectural syntax, thereby increasing the possibilities of interplay between very disparate scales of symbolic values.

"[7] At the crossroads of disciplines, Luis Fernandez-Galiano reminds that "it is frequent to describe Perrault’s work in terms of the great tradition of French geometric monumentality; it is inevitable to relate his bold gestures in this area with that affirmative urbanism which treats nature as voluntary geography; and it is necessary to interpret the almost innocent simplicity of his fundamental drawings in the light of the conceptual or minimal practices which extend up to the limits of ‘land art’ and ‘arte povera’.
