Deconstructivism

 is a development of postmodern architecture that began in the late 1980s. It is influenced by the theory of "Deconstruction", which is a form of semiotic analysis. It is characterized by fragmentation, an interest in manipulating a structure's surface or skin, non-rectilinear shapes which appear to distort and dislocate elements of architecture, such as structure and envelope. The finished visual appearance of buildings that exhibit deconstructivist "styles" is characterized by unpredictabilit y and controlled chaos.
