In 1907, the Clínic Hospital of Barcelona was inaugurated and, with it, the Faculty of Medicine, belonging to the University of Barcelona. With this, the old aspirations of abandoning the buildings on the Rambla dels Estudis, which housed the Faculty of Medicine on its return from Bourbon exile, due to the New Plant decree of 1716, were satisfied. The evolution of medical studies, and specifically the qualitative leap that the 1983 law meant, required an adaptation to the new demands. The main characteristic of this transformation was to create departments dedicated to research and promoting knowledge, the basis of modern universities. To some extent, these transformations have been possible thanks to the quality of the spaces, the formalisation responds to criteria of functional neutrality, which makes the transition from classrooms to laboratories very simple, although these require complex and very specific equipment. The classic outline of the modeling repertoire, in the strictest Beauxartian tradition, has been respected and even improved in some points. It must be emphasised that the grandeur of the common spaces, of a certainly attractive and ritualistic dimension, of something that exceeds the strict necessity, such as the main staircase, the great hall, the cloister or the distribution corridors, imprint a clarity and architectural grandeur that deserved to be preserved. The spatial requirements have forced us to incorporate the basement floor and the floor under the roof, apart from the increase represented by the partition of the classrooms, by means of an intermediate slab. The cores of stairs located on the sides have been relocated centrally in a space where we believe they should have been. In these points, our proposal improves the typological organisation of the classic plan. This staircase gives way to the original and the new floors, introduced through the floor slab partition of levels one and three. The way these new plants reach the façade, in order to avoid the solution of splitting the window in two, led us to make the new level depend on the old one, as if it were a duplex. Therefore, we have built interior stairs arranged parallel to the façade that resolve the vertical connections following a typological rather than a functional order. The façades are composed of windows with stone lintels and jambs, arranged in an orderly manner on a stucco base, which is why its rehabilitation was of special interest. The quality of the stone is not up to the packaging that was intended to be given to the building. It is a stone that has not completed the geological period of formation that corresponded to it, therefore, as easy to work with as it is quick to decompose, especially in the parts most exposed to inclement weather. Once the stones have been cleaned, the shape they had has been recovered, but only as a base to support a sheet of zinc, so that a more complex calligraphy than the original has been incorporated and which gives lightness to a more massive than Doric composition.
