Conceptual architecture
Conceptual architecture is a term used to describe certain buildings that make use of Conceptualism in architecture. These buildings are often less important than the ideas guiding them, ideas represented primarily by texts, diagrams, or art installations. Architects that work in this vein are Diller + Scofidio, Bernard Tschumi and Peter Eisenman. It is characterized by an introduction of ideas or concepts from outside of architecture often as a means of expanding the discipline of architecture.
Conceptual architecture was studied in the essay, Notes on Conceptual Architecture: Towards a Definition by Peter Eisenman in 1970, and again by the Harvard Design Magazine in Fall of 2003 and Winter 2004, by a series of articles under the heading Architecture as Conceptual Art.
