Arch. Giovanni Giorgi has designed the Prometec exhibit booth for Marmo+mac exhibition in Verona. The project aimed to create a welcoming and particular atmosphere, where the protagonist was the customer’s machine. The design wanted to create transparencies that closed the large exhibition space, using white lacquered wooden frames, covered by metal fibre (used to marble working), creating a see-though effect. The wide ceiling has hanged by 24 rigging points, allowing the support of the frames without columns, or vertical structures, in this way the visibility of the customer’s machine has been at 360°. The recessed spotlights have created punctual and dedicated lighting on the exhibit area. The audiovisual communication by Ledwall screens and graphical communication have given a strong visual impact. The project has been awarded as best exhibit booth of the edition of the exhibition.
