Diller Scofidio + Renfro and Stefano Boeri Architetti for the regeneration of “Pirelli 39”

DS+R and SBA’s project is the winning proposal in an international competition launched by investment and development company COIMA in 2019. 70 teams totalling 359 companies from 15 countries entered the competition, and the winning scheme was praised by the jury for its focus on environmental impact, continuity with the urban transformation of the area and the relationship between nature and the city.

The collaborative team composed of Diller Scofidio + Renfro (DS+R) and Stefano Boeri Architetti (SBA) was chosen for the project to reconstruct the site at the centre of Milan’s Porta Nuova Gioia district.
The ‘Pirelli 39’ project involves the renovation of the existing office tower, known as the ‘pirellino’, on the site, which will be adapted to meet current office space standards in terms of innovation and sustainability, while maintaining the building’s original character.

In addition, the construction of a new residential skyscraper will integrate 1,700 square metres of vegetation distributed throughout the structure. The tower will have the capacity to absorb 14 tonnes of CO2 and produce 9 tonnes of oxygen per year – comparable to a 10,000 square metre forest. Thanks to the addition of 2,770 square metres of photovoltaic panels, the tower will be able to produce 65% of its energy needs, while the use of structural wood will reduce its carbon footprint.

Finally, a bridge will be built connecting the two structures, which will also be used as a hub for events, performances and exhibitions. This bridge will also house a greenhouse that will offer immersive and educational experiences such as a dedicated workshop.

“Our studio is thrilled to have this opportunity to make a meaningful architectural contribution to the city of Milan, our first project in Italy.” says Elizabeth Diller, partner at diller scofidio + renfro. “As much of our work focuses on the future of cities, the Pirelli 39 project presents a great opportunity to develop a new model of mixed-use development and sustainable urban growth. the project combines the adaptive reuse of heritage buildings with environmentally responsible new construction, and a vibrant ‘living’ cultural destination devoted to the art and science of plants.”

“This project will reinvigorate the iconic former pirellino building, creating a new tower that mixes architecture and nature to create a green space that is open to the whole city” adds Stefano Boeri, founder of Stefano Boeri Architetti. “In such a difficult period, this project relaunches the vision of a forward-looking Milan and bravely faces the great challenges of the climate crisis.”
