New Eni Headquarters: An innovative and sustainable building 

This is the project for the new Milan headquarters of the Italian energy group, ENI. The structure will be built in the municipality of San Donato Milanese, in the city’s south eastern area.

The project was designed by Morphosis Architects, an American architecture studio led by Thom Mayne, winner of the Pritzker Prize for architecture.

The complex will consist of three executive offices, a company canteen, a conference center and an exhibition hall, with 4600 workstations, in total.

Each executive office will have an independent entrance and bridges connecting it to the other two.
The Icon Tower is the complex’s tallest building, with 11 floors above ground and 1300 workstations.

The Landmark Tower is the largest building, by surface area: 23,000 square meters on over 9 floors.

In the center, the Skygarden Tower building will house the convention hall.
