Deconstructivism, or Deconstruction, is an approach to building design that attempts to view architecture in bits and pieces. The basic elements of architecture are dismantled. Deconstructivist buildings may seem to have no visual logic. They may appear to be made up of unrelated, disharmonious abstract forms. Deconstructive ideas are borrowed from the French philosopher Jacques Derrida.
In the summer of 1988, architect Philip Johnson was instrumental in organizing a Museum of Modern Art (MoMA) exhibit called "Deconstructivist Architecture." Johnson gathered works from seven architects (Eisenman, Gehry, Hadid, Koolhaas, Libeskind, Bernard Tschumi, and Coop Himmelblau) who "intentionally violate the cubes and right angles of modernism."
"The hallmark of deconstructivist architecture is its apparent instability. Though structurally sound, the projects seem to be in states of explosion or collapse....Deconstructivist architecture, however, is not an architecture of decay or demolition. On the contrary, it gains all of its force by challenging the very values of harmony, unity, and stability, proposing instead that flaws are intrinsic to the structure."
