Grenoble Architecture – design by Hérault Arnod Architectes

GMCD Grenoble


Design: Hérault Arnod Architectes

The programme aims to bring together inside a common place all the stakeholders in charge of transport and traffic management within the Grenoble urban region. The objective is to enable autonomous organisations to cohabit and work together: the architecture of the GMCD (Gestion Multimodale Centralisée des Déplacements – Centralised multimodal transport management) arises out of its internal logic. The project functions like a mechanism in which each part is an autonomous element that interacts with the others to form an effective machine.

The future building is an autonomous and sculptural structure, situated at the foot of the DDE headquarters, an imposing and monumental construction built in the 1950s along the “Grands Boulevards”. On the other side of the Avenue, a modern Expressionist church creates a symmetrical counterpart. The two “singular objects” balance each other out, and generate a differential sequence in the regular unfolding of the boulevards.

The programme defines several functional strata, the most difficult of which is the stratum of the service rooms and crisis room, and the way they relate to each other: each CP (Control Point) and its annexes form a whole, expressed on the outside by notches in the structure which separate the different entities. The basic shape of the building is the polygon defined by the contours of the land, but scooped out by the notches that define the profile of each room. For security reasons the CP’s activity must be totally invisible from the street: the exterior envelope is thus totally opaque and the glass parts are grouped inside the notches. At the heart of the building, these notches bring natural light to all the passageways, punctuating them with outside views.

The crisis room is a circular structure, situated centrally, in both layout and cross-section. It has “branches”, which provide direct views to the different CPs and their screens, so that, during “crisis meetings”, information and the changing situation on the ground can be monitored as it happens. This structure within the structure, invisible from the outside, is suspended above the CP itinerary.

In a reference to the multiple screens – fascinating and iconic objects of our time – which will populate the building, the outside walls are covered with a white aluminium skin in front of which are attached natural aluminium discs that form an array of pixels. Behind the discs, the background is lit by diodes, which transform the image of the architecture at night. A computer program will vary the lighting and colour of the diodes, enveloping the building in a changing and communicating skin.
