The stairways have been generously sized and naturally lit to encourage people walk to go from one floor to the next, instead of taking the elevators. The common spaces were created to stimulate interaction and host informal gatherings and meetings. The restaurant and small cafés on the various floors are warm and intimate. Large, furnished terraces are available to anyone who wants to eat outside and enjoy the beautiful view over the wooded park. The three gardens surrounding the building are pedagogical, each one organized around the theme of beneficial, healing, or harmful plants.
