For the reconversion of the site, Gillion conducted an analysis of the district and its needs. The future building had to integrate three functions : student housing with an ideal location between ULB and VUB, a business well located in the Chaussée de Boondael and parking, which is hard to find in the district.
Due to the size constraint to obtain the permit, the urban planning required the preservation of the existing façade, which meant adapting the architectural plans to respect the windows and heights under ceilings of the old residence. From the point of view of building energy performance (BEP), the building therefore combined two distinct working methods: first, heavy renovation and second, new construction. The new building, with its modern white façade, will be juxtaposed against the old façade to form a single building. However, the exterior will give the impression of two separate buildings.
