Public area of the Saisons district

 The surroundings of the Alto tower are treated, on the boulevard side, as a large topographical forecourt predominantly mineral. The steepest part becomes a succession of large steps in which vegetation is integrated. This forecourt, which extends on the Alto parking area, covers the current hole between the boulevard and the Seasons slab. It allows to signal the tower and the Saisons district on the boulevard, and above all to connect the different levels linked to the Allée Louis Blanc (31.90m), the ring boulevard (37.00m), the Seasons slab (41.50m) and the accesses created by the Alto project (upper and lower entrance to the tower, shops in the square and access to the Alto parking area).
The project redevelops several vertical connections including PRM (Person with Reduced Mobility) access (slopes <4% and elevators) to the different levels. On the back of the tower, slab level, the project impacts the existing layout by removing access to the Seasons building (double walkway), and creates a roadway between the future forecourt and the Place des Saisons and also modifies the garden area in l’Ancre parking. The layout on the slab are mainly based on these constraints: creation of a garden with setings in the continuity of the existing facilities. Last but not least, the landscape design reduces the presence of strong wind in this area.
