"Much of Gehry's work falls within the style of Deconstructivism. Decontructivism, also known as DeCon Architecture, is often referred to as post-structuralist in nature for its ability to go beyond current modalities of structural definition. In architecture, its application tends to depart from modernism in its inherent criticism of culturally inherited givens such as societal goals and functional necessity. Because of this, unlike early modernist structures, DeCon structures are not required to reflect specific social or universal ideas, such as speed or universality of form, and they do not reflect a belief that form follows function. Gehry's own Santa Monica residence is a commonly cited example of deconstructivist architecture, as it was so drastically divorced from its original context, and, in such a manner, as to subvert its original spatial intention.
Gehry’s style at times seems unfinished or even crude, but his work is consistent with the California ‘funk’ art movement in the 1960s and early 1970s, which featured the use of inexpensive found objects and non-traditional media such as clay to make serious art. Gehry has been called ‘the apostle of chain-link fencing and corrugated metal siding‘ (B. Adams). However, a retrospective exhibit at the Whitney Museum (New York) in 1988 revealed that he is also a sophisticated classical artist, who knows European art history and contemporary sculpture and painting."
