The project is focused on health and biotechnology.

Co-founded by Paris Descartes, ESSEC, Centrale Paris and INSERM, jointly financed by Ministère de la Recherche, Ville de Paris and Région Ile de France, Paris Biotech Santé has been operating an incubator for innovative companies specialised in the development of medicine, medical devices and innovative services to benefit patients. Although still at the project stage, it provides companies with offices, services and advice.

Completed 2007, the first phase was entirely located on the hospital site. Like a campus, the site accommodates buildings with different architectures, each indicative of its era.

The second phase at the front of the site on Rue de la Santé gives the building a different aspect.

Animated by setbacks that play with the perspectives, the complex building shape is expressed as an interlocking volume. In extension of the satin copper clad first phase at ground level, is a volume in contact with the sky - clad in white glass, both smooth and reflective, punctuated with yellow blades.

The second phase introduces a new element within the incubator - a 4-level central atrium. One of its walls, a first phase elevation retains its reflective copper panels.

 The atrium has a lobby on the ground floor, a central place conducive to encounters, an essential component in a research facility at this scale.

The two floors above the atrium extend in corbel above a terrace in the first phase, unsupported by the existing building.

 Despite the atrium void, the research facility provides the floor space required by the programme.

In compliance with Parisian planning regulations, planting makes it possible to store and evaporate rainwater, without discharging it into storm water drains. Moreover, it provides researchers with a very pleasant outdoor space with a breathtaking view of the Val de Grace dome.
