The building is connected to the Terminal 1 terminal by a 200 m pedestrian walkway that crosses the road. The building, of rectangular plan, is characterized by the large windows of the structural facades equipped with high quality glazing.

The emergency staircase on the north side of the building, made of metal carpentry, with grating galvanized steel steps, is completely covered with a galvanized steel grid. The structure of the new building is in reinforced concrete cast in situ, up to the floor of the ground floor and in steel for the floors above ground. The beams of the floors and the columns are made up of hot-profiled elements, while the floors are made of corrugated sheets of the type cooperating with the completion casting in concrete and welded mesh. The staircases and elevators are in reinforced concrete cast in situ, while the foundations are of the direct type with continuous beams and with stalls for the stairwells. The external envelope of the building consists of a semi-structural façade with uprights and crosspieces in aluminum with "thermal break"; the façade is made with three alternating mirrors of insulated blind panels and double-glazed windows, Inside the building the partitions are made by dividing walls, made with modular blind and glazed movable walls.
