Like Siah Armajani, whose Bridge for Robert Venturi is also on view in this gallery, American conceptual artist Dan Graham employs models as well as life-size architectural units that examine space and material and their relation to the environment. In Alteration to a Suburban House, clear glass replaces the façade of a suburban home while the interior space is bisected by a mirror. By exposing the home’s inhabitants and reflecting the environment it faces, Graham investigates the boundaries of public and private, providing an ironic commentary on the utopian ideal of suburban life and social conformity.
