The project is the result of an association between 3 architecture studios: Beretta Associati, AR.CH.IT Luca Cipelletti and Bernard Dubois. The architectural composition finds its geometrical reason in a radial structure made of wood that proceeds from the outside to a central, lighted trunk and salt with a progressive twist of the structure and plans. The choice of a central plan is both functional and structural. The choice of a wood structure is in line with a sustainable approach to the project and the call for a very fast construction site. The use of wood is both traditional and innovative. Traditional for its constant recurrence of use in time and space; innovative, especially with regard to Italy, where the wood has always been used more in craft works than for structural purposes. The project intends to promote a spontaneous interchange between inside and outside, as well as induce a progressive enlargement of the perception of space thanks to the arrangement of the branched beams that lead the visitor to discover fluidly the Pavilion in direction of the facades. The design of the green spaces offers visitors a dynamic and evocative experience: the patio, for instance, recalls the Italian landscape of cultivated terraces, or the panoramic terrace where the cultivation of different vegetable, fruit trees and herbs becomes didactic and related to the theme of EXPO 2015. Every aspect of the project responds to the need for an iconic place, perceived in its plurality; the design facilitates the relationship with the exhibition context of EXPO as well as its integrated nature guarantees its own durability and reconversion for the future.
