The car park is located between two office blocks and a metro tunnel.

The structure is a cylinder of 40 m diameter comprising the following:
– a circular diaphragm wall, excavated to a depth of 28m, in a marl soil,
– a cylindrical, reinforced concrete central core 22m high, housing the vertical connections,
– a continuous helical ramp running down 7 levels and carried on radial beams, with about 40 parking spaces for light vehicles on each level on either side of the two-way ramp,
– a cover slab supporting the new architectural features and a new road across the square.

The technical and secondary work was carried out after completion of the associated works (ventilation shafts, lift, operations room).
