New Headquarters of the AP-HP

Respect for the existing environment, the preservation of views as well as optimal and flexible functionality over time are all conditions that guided the placement and volume. The design of the facades is based on a sober and largely glazed architectural reading, highlighting the transparent base and the slender balconies.

For the balance of the site, we propose to find a new green heart compatible with the new programme.  By planting on top of all of the programmes located in the base and by reconstituting a hilly landscape, we create a gentle topography inviting people to walk on this new ground.

A place with trees, this planted area will be the centre of exchanges. The layout of the garden is designed to increase the permeable surfaces and to accentuate the planted landscape continuity. The plant species have been chosen from among those indigenous to the Ile-de-France region.

The continuation of our research on how to host life finds its application here through the development of a living concrete wall¹ in collaboration with the contractor CBC. In continuity with the garden, this perimeter wall with a surface area of 390 m² surrounds the auditorium that carries the hill. The substrate forms a continuum, from the permeable ground to the roof garden.
