Research for Research is part of an ambitious undertaking that strives at no less than to rewrite the history of urban planning of the twentieth century as a history of research. In this research we analysed a series of canonized urban proposals and theories on the basis of three questions. First: wat kind of research were these projects based on concerning the real situation as found? Second: what kind of political and bureaucratic system did the projects presuppose in order to be realized? Third: what state of technology did the projects presuppose? This leads to a history that is not so much a history of visions, but a history of interpretations and extrapolations of the real.
