Deconstructivism is an architectural movement that began in the late 1980s characterized by fragmentation and unpredictability. It rejects traditional ideas of order and form by exploding buildings into loose collections of fragments. Prominent deconstructivist architects include Zaha Hadid, Frank Gehry, Daniel Libeskind, and Rem Koolhas. Their buildings use unconventional shapes and geometries to provoke uncertainty through challenging conventions.
