The three office towers, with their peculiar curved planimetric shape, embrace the square, shielding it from the chaos of the city and emphasizing the intimacy of this new elevated meeting place. Towards the park, the circle opens bending towards the south (in correspondence with the office building by Piuarch), thus underlining the continuity with the new green space. The project is signed by Pelli Clarke Pelli Architects.

The increasing height of the three towers (11, 22 and 31 floors respectively) determines the characteristic spiral configuration, culminating in the spire, the highest spire of the UniCredit Tower, conceived by Cesar Pelli as a landmark par excellence of contemporary Milan.

The extensive use of mirrored glass for the elevations determines the overall evanescence of the complex that, despite its size, is iridescent to the variations of light throughout the day and ends up dematerializing in the urban landscape that is reflected in it. All the buildings have been awarded LEED Gold certification, testifying to the importance that the issue of all-round sustainability has had in every phase of design and construction.

The extensive use of mirrored glass and curved facade elevations result in a variation of light reflections throughout the day. The three towers have been covered with energy-efficient cellular curtain walls produced by the company PERMASTEELISA. The project involved the installation of 48,000 square meters of cellular curtain walls, 16,000 square meters of stone ventilated facades and 6,000 square meters of sunshades. All the buildings have obtained LEED Gold certification, demonstrating the importance that the issue of all-round sustainability has had in every phase of design and construction.

The cellular façade consists of prefabricated units measuring 1.50x4.00 m. These units are composed of four elements: 3 visual glasses, with high thermal, luminous and acoustic performances, and 1 spandrel in correspondence of the floors. The curvilinear course of the facade makes some cells concave and others convex. The different reflectance of the glasses composing the façade, together with their shape, determine different reflections and thus skipping the shapes of the buildings.

Tower C, consisting of 11 floors, is about 50 m high; Tower B, consisting of 22 floors, is 100 m high; Tower C, consisting of 31 floors, reaches a height of 218 m with only the spire being 78 m high.
