The cultural hub Antipode is constructed in the new concerted development zone of the eco-district of La Courrouze, two kilometers away from the historic center of Rennes with very good tramways and soft mobility connections. Urban planners Secchi and Vigano organized the various programmes like large islets flooded by vegetation. The site is a vast territory on which were historically armament factories. To make its memory last, some walls have been preserved as well as large trees that punctuate the horizon.

The project is part of a very open urban landscape. The building is flooded with greenery in this wooded universe, a phenomenon that will increase with time. The structure will reveal itself through the large oak trees, a filtered vision through the canopy. Like a castle in its park, the building, as if concealed, will emerge through this vegetal universe. For this wealthy programme, the objective was to weave relationships between very different architectural elements.

The agora connects blocks as different as a current music scene, a media library, music rehearsal spaces, a Youth cultural center, music and recording studios, dance rooms and a creation and rehearsal space. The challenge was to bring them all together while taking advantage of the unusual proximity of such cultural services.

Around a central agora with an added patio, the spaces are intermingled, fused so that it connects the elements of the plan intended for public use such as the bar, the exhibition space or the conference room. The building covers the site generously and occupies the entire plot. The spaces seem to be positioned side by side with no apparent hierarchy.

The project is drawn like an extended and compact mass from which the empty spaces have been removed. The natural light irrigates the spaces thanks to the four patios and some terraces. The visitor is constantly drawn to these interior exteriors which stand as landmarks. The empty zones visible in the sectional arrangement and the numerous sectional drawings create micro-spaces.

The almost maze like layouts reveal the complexity of the interweaving programmes and their layers. Like a Raum, the unusual scaled plan emphasizes an apparent absence of hierarchy. The crossings and intertwining paths are aimed at better highlighting the programmes.

Here is an architecture of the interstice, an architecture of the crevice. On the outside, the black mass of the building contrasts with the luminosity of the interior spaces. The media library catches the light on all four sides as if it were evading from this thick, compact mass.

We were able to reduce the building's carbon footprint in a number of ways: energy management (natural light, green roof, airtightness), eco-responsibility (low-pollution site, use of sustainable wood, eco-labelled paint, water-saving appliances, wastewater management) and durability (concrete structure and external insulation = 50 years and 14 years of durability).
