EXAT 51 (the name stands for "Experimental Atelier") was a group of artists and architects (1951–56) whose program was geometric abstraction in painting, new ways of handling of space in architecture, and the abolition of the distinction between fine and applied arts. Their ideas owed much to the Russian Constructivist avant-garde and the German Bauhaus experience, and Exat wanted to involve artists in the shaping of the environment with an experimental and creative approach. Members of the group included architects Bernardo Bernardi, Zdravko Bregovac, Zvonimir Radić, Božidar Rašica, Vjenceslav Richter, Vladimir Zarahović, and painters Vlado Kristl, Ivan Picelj, Božidar Rašica, and Aleksandar Srnec.
