EPFL GA building

The site occupies a particular position in the southeast corner of the lots destined for the EPFL. The project proposes to build along this angle, with alignments along the south face and the east face. The new building will house a variety of programmes, and will be developed on the principle of layering. Each floor thus has its own layout logic, based on a stacking principle. In this way each typology is adjusted to the layout, without being subject to the constraints of the logic applied on other floors. This adjustment allows for a layout distribution giving direct means of access to outside facilities on the same levels.

On the ground floor, arranged around a tree-lined patio, are the kindergarten, the UAPE (extra-curricular centre), the administration and the cafeteria. On the first floor there are the three units of the day nursery. The second, third and fourth floors are occupied by the Science Promotion Service and EPFL rooms. The overlay of floors is effected by a system of concrete slabs and frontage string courses to protect the facades from the weather and create shade and protection from the sun in the summer months. The offset layout of the concrete parapets gives a strong image and identity which corresponds to the position of the building on the EPFL site.
This principle is adapted to the flexibility required by the project: a building height of Ground floor + 2, or Ground floor + 4, making it possible to also raise the building so as to reach a height of Ground Floor + 7.
