U3 Building

Milanofiori Sviluppo Immobiliare srl has commissioned GBPA Architects to design the new U3 building for tertiary use in the urban sector of Milanofiori in Assago.

The project develops the typology of the directional building in line, with double body, placed perpendicularly to the highway A7, position that gives it a great visibility.

The building of about 12,000 square meters. consists of nine floors above the level of the existing elevated square and two floors, below, at destination parking.

The building looks like a transparent volume, closed between two light wings. On the highway, the front is narrow and soaring; on the back, facing the green area, the front opens onto terraces and is designed to enjoy views of the park, the green heart of the’built of milanofiori. The north and south views define the image of the building, which is characterized by a particular and moving effect, played by the refraction of light on the blinds, differently oriented, in white screen-printed glass.

The southern façade, in particular, seems to be suspended, revealing the transparent rectangular volume that reinforces the relationship between inside and outside. The reception, as the focal point of access, is given a certain visual position thanks to the frame of two opaque fifths.

The building meets the criteria of green building with LEED GOLD certification.

Perfectly integrated into the area but, at the same time, with a clear identity of its own

U3 is located on the western edge of the area, adjacent to the Milan-Genoa motorway. It is an in-line, double-body building, which is developed perpendicular to the carriageways in order to turn as little space as possible to traffic, so that the offices are not affected by noise and pollution.

The complex is surrounded by greenery and overlooks the central park of the Milanofiori area.

The Hall space is designed to connect the different elevations of the project area and all accesses to the functions located on the various floors of the building are accessible from one central core.

The floor plan of the typical floor provides maximum flexibility for the benefit of tenants with different possible fit-outs. The lifts and bathroom cores have been placed in a barycentric position in relation to the whole floor to ensure more rationality in the horizontal pathways on the floor.

The façade is built with modular, cellular frames in two sizes: 300×400(h) cm and 150×400(h) cm, spaced on a structural module of 9 linear metres. Blades made of a new generation composite material, “solid surface”, are attached to this modular type of façade.

The blades are of three sizes and positioned at different and progressive angles, so as to give the façade a particular curvilinear and continuous course.
