The Institut d’Études Politiques

Chapuis Royer architectes as Architects

Built in 1965, the Institut d’études politiques (IEP, or School of Political Science) had a rather less exceptional façade which had begun to deteriorate. No longer compliant with any building codes, it had to be fully rehabilitated and enhanced with an extension in order to provide what it lacked in its initial program. Standing at the intersection of three major axes and in close proximity to the campus tram station, it benefits from a highly strategic location.

To enhance its status, the decision was made to take advantage of the rhythm of the existing structure of alternating raw concrete columns/beams, screen walls and sunshades, to design an extension that literally blends into the initial construction, giving it a new lease on life and a beautiful architectural presence. Today it is virtually impossible to tell the old section of the building from the new one.

All concrete elements were poured in place, including exterior and interior staircases. To fully achieve symbiosis of old and new, two types of forms were used: a metal form, for the plinths and the parapet walls resulting in a smooth concrete, virtually identical to rehabilitated concrete of the original columns/beams; wood, the other material used for pouring forms, recalls the existing screen walls decorating the west façade.
