Architecture competitions can, as experimental processes, be seen as epistemic spaces for the production of disciplinary knowledge. Building on the model developed by philosopher of science Bruno Latour, highlighting the transfers of power between the scientific laboratory and the world, architecture competitions can be used as political levers enabling work within the laboratory to expand beyond its walls in order to transform the world. This essay examines the architectural competitions projects understood as 'avant-garde' in a corpus of architectural writings published from 1932 to 2012, and highlights those critical aspects that allow their ideological and cultural function unfold towards the transformative powers of the discipline and of its becoming as political lever.
