Abstract
To understand the specific work of the architect, it is essential to reflect on the epistemological status of the project, to engage in a kind of hand-to-hand combat with the operations, concepts and representations used in the various stages of the design process. The questions addressed, which are at the heart of a book currently in preparation, lie between the archive - in the sense Michel Foucault gave to this notion, captured in its formation, design research - and space, the real implicit material of the project on the city.
