A new campus in 2025

iXcampus Saint-Germain-en-Laye has embarked on an ambitious development program to double the current size of the campus to accommodate 870 students and 900 employees by 2025.

The campus transformation will integrate into its natural environment and minimize its impact on it. Passive buildings, biophilic design and low carbon construction are at the heart of the project.
The roadmap assigned to the architects Baumschlager Eberle, winners of the competition launched in 2022 by iXcampus:
  • To build reversible sustainable buildings aiming at carbon neutrality, taking advantage of their usage to move towards zero consumption, and generating a positive impact on their environment and the site’s biodiversity.
  • To design a real estate complex that can accommodate any type of program over the long term, and to allow future uses without modifying the structures already in place.
  • To enable the emergence of human and technological synergies thanks to innovative spaces, and to allow stakeholders from the worlds of business, research and higher education to interact with one another.
