Architects produce diagrams, not buildings, but diagrams that are wholly immanent, wholly embedded and coextensive with the materials, configurations, and forms of buildings. Theories of representation and expression have tended to privilege the concept over the building, treating the artifact as a site of interpretation, a mere extension of the process of its production. But if such concepts could be adequately expressed or understood separately from their manifestations, then the buildings themselves would be unnecessary. Architectural concepts only exist fully in their realization, as discoveries through the non-linear process called design. That condition of immanence inspires the recurring attention to method and process in the architectural discourse and equally the frustration with the embedded quality of the theorizing that it reveals.
