Hello aspirant.

Deconstructivism is a movement of postmodern architecture  which appeared in the 1980s. It gives the impression of the fragmentation of the constructed building. It is characterized by an absence of harmony, continuity, or symmetry.Its name comes from the idea of " Deconstruction  ", a form of semiotic  analysis developed by the French philosopher Jacques Derrida .

You may call deconstructivism as destructive architechture.

Hope this will help you.
