The entrance to the base of the company , located into an antique industrial factory, has been restyled. Inside of a doubled height volume, long 90 meters, a steel staircase is articulated into the space. This feature allows to recognize two different areas: a visitors way, trough the workshop and the researchers laboratories. A sun belt highlights the sinuosity of the raised route, which helps to perceive the levity of the structure itself. A compass organizes the entrance and the exit flow.
