Central to this vision is the new staircase. Each of the 10 floors of the building has a social hub including a cafeteria and play area. In order to encourage socializing and interaction between the 2000 employees through mobility between levels, the slabs were cut and sculptural stairs were installed to unite vertically the social hubs among floors. The staircase is a metaphor for the thread and fabric, related to the heritage and the prestigious factory visible across the street, "A.P.A.C.A." (Army Garment Factory).

The stairs are our own “Ago, Filo e Nodo” Monument (the monument that celebrates Milan's textile tradition). The banister recalls a sewing rope and the elastic stainless steel mesh is a transparent metaphor for the fabric. The stair puts together the layers of the building and reinforces the social fabric the same way as the thread and needle puts together layers of textiles. The treads are in monolith cast terrazzo and the mono stringer is in metal, mechanically bonded together. As a part of the same metaphor, the streamlined shape recalls the anatomical spine and vertebrae.
