It is impossible to dissociate the evolution of Enric Miralles' architecture from the development of his own system of representation. Founded on an initial position inherited from his training at the Barcelona School of Architecture and his practice at the office of Viaplana-Piñón, where he acquired a liking for precision in drawing and a graphic style based exclusively on lines of the same thickness, Miralles soon developed a method defined by a customised use of orthographic projections, connected to a fragmented conception of the architectural plan and space itself. The Miralles Projection explains both the origin and evolution of Miralles' system of representation, from his time as an architecture student and collaborator at Viaplana-Piñón to the latest projects he designed with Benedetta Tagliabue, including the important period with Carme Pinós. With a curated selection of previously unpublished drawings, it demonstrates on a fundamental level how the evolution of his architecture ran parallel to that of representation, thus illustrating their indissolubility and mutual interdependence.
