OMA and Milan-based Laboratorio Permanente have won a competition to transform two abandoned railway yards in Milan into eco parks that will act as “ecological filters” for the car-centric city. Titled Agenti Climatici (Climatic Agents), the master plan would use the natural, air-purifying power of plants and the filtering capabilities of water to clean and cool the environment while adding new recreational spaces for the public. The project is part of a larger effort to redevelop disused post-industrial areas around the periphery of the city.

The Agenti Climatici master plan addresses two railway yards: the 468,301-square-meter Scalo Farini on the north side of Milan and the 140,199-square-meter Scalo San Cristoforo on the south side of the city. The designers have designated Scalo Farini as the “green zone” that will consist of a large park capable of cooling the hot winds from the southwest and reducing air pollution. Scalo San Cristoforo has been dubbed the “blue zone” after the designers’ plan to turn the railway yard into a linear waterway that will naturally purify runoff and create cooling microclimates.

“In a moment of dramatic environmental transformation and permanent economic uncertainty, our priorities have changed,” said OMA partner Ippolito Pestellini Laparelli. “The most valuable currency is no longer ‘brick’ — the built — but rather the climatic conditions that cities will be able to provide and ensure for their citizens. The city of the 20th century, with its high energy consumption, must be overcome by reconsidering the principles that have marked urban development since the classical era.”

For adaptability, only the public elements of the Farini park will be fixed — including the waterways, greenery and bridges — while the location of the buildings and their programming will be contingent on the city’s future economic development. The master plan also calls for Milan’s longest expressway bicycle lane alongside a new tram line and metro stations.
