The new facilities are accessible since the 2017 academic year, increasing the surface area of the main Saint-Louis campus from 25,000 m² to 47,000 m².[15]

Saint-Louis University is located on two campuses in Brussels and Ixelles. The main campus, Saint-Louis, with 48 km² of university space, is located in the city centre, between the rue de l'Ommegang and du Marais, as well as the boulevards du Jardin botanique and Pachéco.[15] The campus is split in two by the Institut secondaire Saint-Louis, forming to the north the "Botanique" and "Préfecture" buildings housing the Institute of European Studies (Marais 119), the university press (Botanique 42), the university's official main building (Botanique 43) and the historical building with the rectorate (Botanique 38) and the former library; and to the south the more recent Marais 109 and Ommegang buildings, where the faculty and student administrations are located, and several large auditoriums.[16]

The courses of the Marie Haps Faculty Translation & Interpreting are given on the Marie-Haps campus, shared with the Haute École Vinci, in Ixelles, in the European quarter, more precisely in front of the European Parliament. The buildings of the Marie-Haps campus are located on either side of rue d'Arlon and historically in the Hôtel Beernaert.[16] The language courses (extra-curricular) are given in an office building further north, between rue d'Arlon and rue de Trèves, where Marie-Haps' Dutch-speaking departments (which have integrated the Erasmushogeschool Brussel and Vlekho) used to be located.

The Marie-Haps Faculty is also located on the Tilleuls site, former Œuvre du Calvaire hospital, which integrated the Saint-Luc University Hospital in UCLouvain Brussels Woluwe in 2003. The Tilleuls site includes a large country house, a caretaker's house, a chapel and the former hospital transformed into classrooms, located on the Chaussée de Wavre.
