The second skyscraper built in the CityLife district, known as “Lo Storto” (“The Twisted One”), serves as the main headquarters of Assicurazioni Generali. Its high energy efficiency, use of renewable energy sources, and advanced envelope solutions have earned it the highest level of LEED certification
The tower features a rhomboid floor plan and a sequence of floors that rotate around a vertical axis. This twisting motion gradually lessens as the height increases, becoming fully vertical near the 40th floor. The building ensures full transparency in all directions, without interruption.
Office spaces are distributed across 40 floors, while the remaining four above ground host technical systems and a striking double-height entrance hall. Two additional underground levels accommodate a parking area and the main mechanical rooms.
A double-skin unitized façade, district heating, and a ceiling-integrated chilled beam system ensure excellent indoor comfort and high energy performance.
Sustainability was a central focus in the design, with particular attention to:
Automation and building management systems support both environmental control, particularly of lighting and climate, and continuous monitoring of major equipment, enabling timely maintenance and prevention of failures. Given the building’s strategic role, it is also equipped with high-performance security and safety systems.

The redevelopment project transformed the former State Printing Office into Enel’s new headquarters.

The redevelopment project of the complex at Corso Italia 23, in the heart of Milan, has transformed an iconic 1960s building into a contemporary, high-performance campus, which in September 2024 became Deloitte’s new Milan headquarters

The new Prysmian Headquarters recalls the industrial root of Milan’s Bicocca district.
