The emphasis in the design is on contrast between squared-off volumes, such as the outside of some of the buildings, and sinuous spaces such as the interiors in customer and staff areas.
The parallelepiped with 2 splayed sides is the warehouse, resting on a concrete base about 2 metres high, for automated robot-operated storage. The cement base is intentionally left rough, with an irregular texture, like a "root" of the building emerging out of the ground and contrasting with the building's perfectly smooth, opaque skin.
The load-bearing structure is made of steel, but it is clad in insulated panels and plates of zinc-titanium alloy with a dark slate grey surface patina.The connecting building is about 57 metres long, with a maximum height of 12 metres and a load-bearing structure consisting of a series of 5 arches of various heights made with steel profiles. Here the cladding is concave, with a double skin painted black.
