The building expands the Milanofiori Nord Masterplan which includes two new buildings in the North-West area: the so-called "cliff", a group of buildings that surround the urban development. The neighbourhood takes on the clear and recognizable role of a landmark between the city and the hinterland.
With its 15 floors above ground and approximately 31,500 square meters of surface, U1 is one of the most notable achievements in the sector. The plurality of architectural styles is enriched by the shape that combines volumetric needs with the respect of the alignments of the Masterplan
The U1 has a sort of bow, elevated towards the North-West. This glass and steel blade becomes the fulcrum of the building's architectural composition. The two fronts of the development branch off from it. The body facing the highway is the largest and highest. The uniformity of its glass surface is "broken" by the dense rhythm of vertical elements and horizontal string courses, creating protection from the sun and a barrier to noise. The shorter front of the building, facing north towards the woods, achieves maximum transparency thanks to the glazed façade. Its position allows greater permeability and the relationship with the surrounding environment becomes more intense. The perception of the natural space is as direct as possible.
