Our proposal is a response to the concrete challenges of opening the campus to the city. 
We have thus proposed an implantation of the two buildings (35 and 36) which opens the garden of Egger's initial plan by a completely free passage on the first floor of building 36, the Shared Resources building, which thus connects the city with the Place Eugène Bataillon to the garden, the heart of the campus.

It accompanies and shapes an open path from the urban public space of Place Eugène Bataillon to the garden, the heart of the Campus, it is a showcase, a large open door on the campus. The façade on Eugène Bataillon Square is treated in an urban manner and features a moucharabieh, solar protection for the teaching premises, but exposing the names of famous scientists through a set of perforations, in binary language.

The Biology-Ecology building (Building 35) reinterprets this idea of a journey in a vertical stratification. The different levels, enlarged by their lateral walkways, are superimposed like so many first floors and are connected by vast staircases which constitute a continuous path between the different levels.
