The structure is made up of four buildings interrupted by two triple-height glazed bioclimatic greenhouses characterized by the presence of green areas, places of relation which connect the various buildings intended for offices. Designed by the architect Maurizio Varratta, the Prysmian Group’s new headquarters is built in the Bicocca district and even its shape, similar to a typical Lombard factory, recalls the industrial roots of this area of Milan. In fact, the complex consists of four wings, used for offices and services, connected by two large “greenhouses”, i.e. full-height glazed areas intended for internal mobility. The “greenhouses” are real oases of greenery and, thanks to the presence of plenty of vegetation and water tanks, make a significant contribution towards improving energy efficiency and the internal microclimate. Moreover, the winter gardens are designed as bioclimatic and biophilic meeting spaces. External movable shading, internal light diffusing texture and dedicated planting create an inspiring space fostering collaboration and a sense of connection to nature. Another feature of the building is therefore the extensive use of natural light thanks to extensive glazing. The complex includes the renovation of the Group’s historic optical fibre spinning tower and also houses an auditorium and a staff training centre. The building has been awarded with the LEED V3 New Construction Platinum level with 85 points out of 110, among the highest progresses in Italy.
