Diller Scofidio + Renfro is a New York City based architectural firm founded by Elizabeth Diller and Ricardo Scofidio. They are particularly well known for their interdisciplinary approach to architecture. Their influence stems as much, if not more, from their contributions to the theory and criticism of architecture as from their built works. These are sometimes in the form of written work, but more often are in the form of installation art, video art or electronic art.
