The respect of pre-existences and the extreme strictness of the choice of materials -rough concrete, black and white metal- and of colors -grey, white and natural iron- and the choice of drawing all the white metal elements folded like sheets of paper with irregular geometries, create a unique atmosphere, with a continuous contrast between the rough and the smooth, the light and the dark, the well-defined and the undefined. Display cabinets and work tables are in white metal, folded like paper, variously arranged out.
Two inner courts are the background to the various spaces.
