This whole project has been played around the opposition of different materials and their finishes (the brutality of rust iron sheets contrasts here with aseptic mirror-polished stainless steel, sand-blasted glass and the marble of the floor covering, as well as with the delicacy of the wax-finished stucco of the walls) and the systematic repetition of a negative plastic element, the hole, used with both decorative and functional meanings. A carinated partition with a lining profile (entirely covered with sheets of mirror-polished stainless steel fixed with aluminium bolts) defines a short passage leading to the laboratory and the toilets, enhanced by a line of white and brown marble inlaid in the black marble tiles of the floor. One of the walls of the main room is split in two wide converging surfaces entirely covered by rust iron sheets fixed to their structure with hundreds of copper bolts; the concavity of such wall contains a sand-blasted glass shelf, to be used for standing snacks. Wall lights and coffee tables have been expressly designed for this place.
