In his first period, he developed sculptures of an architectural scale, walkable buildings, and references to the theater and its devices.
In 1996 he began working with videos, in the form of micro-narratives where the characters are confronted with objects, sets, and props.
The video series Anarchitekton (2002–2004),[1] is one of his most emblematic; in the four cities of Barcelona, Bucharest, Brasília, and Osaka, the character called Idroj Sanicne carries cardboard models and replicas of real buildings.
In 2008 the Galerie Nationale du Jeu de Paume in Paris hosted a major retrospective exhibition of his work.
He is represented in numerous museums and collections: Museo Reina Sofia, Madrid, Centre Georges Pompidou, Paris, MUMOK, Vienna, MACBA, Barcelona.
