The Pasrel project is part of the Corbeille mixed development zone on the Paris-Saclay plateau, in an area undergoing major demographic and urban transformation.

The aim is to create a building that is both urban and functional, linked to the GHNE hospital, and integrated into a mixed neighbourhood combining research, teaching, housing and services. Located on the edge of the hospital, the building fulfils several functions: support for research, patient care, access point to the GHNE, and a place for training.
