Torre Unipol, Office skyscraper in Porta Nuova, Milan, Italy

Torre Unipol is an office skyscraper with 23 above-ground floors and 3 underground levels, distinguished by its modern glass and steel structure. The building houses office spaces and commercial areas within Milan's business quarter.

Construction began in 2017 and was completed in 2023, marking a six-year development in Milan's business quarter. The project emerged as part of the ongoing modernization of the Porta Nuova neighborhood.

The tower stands where the Hotel Gilli was once planned, at the corner of Via Melchiorre Gioia and Via Fratelli Castiglioni. Its X-shaped steel cladding, made by the Treviso firm Maeg Costruzioni, is meant to resemble a nest. The rooftop greenhouse-garden and panoramic terrace are designed to host cultural events such as exhibitions.

The tower is located in Porta Nuova, a central and easily accessible area of Milan with good transportation links. Visitors can view the exterior facade, but interior spaces are offices not open to the public.

The facade's X-shaped steel lattice, made by Maeg Costruzioni of Treviso, is meant to resemble a nest. Behind it, a double cavity along the outer walls buffers summer heat and winter cold, and solar panels generate electricity. Winter gardens on the perimeter terraces and the roof help regulate the interior temperature, cutting reliance on mechanical ventilation near the atrium.
