The two buildings, the new and the existing, are connected by two pedestrian bridges at the second floor and the new expansion is subdivided, analogally to the existing, in three blocks, visibly bigger in term of volume than the one faced.
In net constrast with the old Ministry, which the design intention was to have it "floating" on a sort of heavy podium at the ground floor, the new is conceived to extend as much as possible the public character of the building and the public realm of the ground floor.
