4 Unit Tool Steel Hollow Square

Carl Andre's "4 Unit Tool Steel Hollow Square" (1969) exemplifies the artist's minimalist approach through an arrangement of industrial steel units configured into a square formation with a void at its center. The work demonstrates Andre's characteristic use of readily available materials and modular repetition to create sculptures that emphasize the relationship between the artwork and the viewer's physical space rather than traditional formal composition. As a floor based piece, it invites viewers to walk around and through the work, challenging conventional notions of sculpture's pedestal and encouraging direct spatial engagement.
