It is no longer the autonomous art object that counts. The work becomes subordinated to the requirements of the site, and the final result may not even be immediately recognizable as a work of art. As indicated above, interdisciplinary collaboration implies a change in production and working methods in which, ideally, a professional exchange of ideas and concepts takes place on an equal level, and the ultimate functional purpose of the project, its service to the public, outweighs even the personal esthetic. And ideally, the result will be a work of art whose existence is justified by its relationship to the environment and its multiple social, political and cultural layers as a whole.
