At the edge of the historic town center, the St Roch redevelopment zone is an area reclaimed from a railway yard. Here, urban renewal must contribute to the emergence of a new lively, open, mixed-use and sustainable neighborhood.
The urban puzzle coming together here includes lot III, which occupies a particularly strategic and privileged place as its height of 50 meters it symbolizes the gateway to the new neighborhood and as such, must link the two urban histories. This is why the project has been developed based on the concept of superimposing two registers.
The first register addressing the historic town center, the lower section of the city, is represented by a stone base of varying heights. Like a ribbon of stone, its architectural orthogonality joins the programs that form the superblock. It includes a base of shops and a six-story office building facing the train station. The second, the Higher Roch Tower, dialogues with the distant city heights, its variable geometry creating an organic appearance containing 82 apartments on 16 levels.
The undulating forms of the plateaus and terraces reminiscent of contour lines on a map are stacked and staggered. These overhangs are linked by a giant piece of metal mesh. The apartments were designed with the climate in mind, resulting in a Mediterranean tower offering the additional uses and fluidity between the inside and the outside afforded by the presence of very generous terraces. Thus, the exterior areas are designed as a continuous series of outsized living areas between sunlight and shade.
