Since Expo 2015 onwards, Milan has been undergoing a series of significant transformations that have profoundly changed, and are changing, its urban layout at the most disparate scales, but according to a common denominator: the regeneration of the built environment, in a period when the consumption of land is less and less feasible for reasons that are not only spatial but above all ethical. From the regeneration of railway terminals, huge former industrial suburbs and unresolved urban nodes to the renovation and valorization of historic buildings, parks and roads epitomizing Milan’s urbanitas, Milan is projecting itself towards the future as an international capital, outstanding in services, culture, sustainability and, last but not least, territorial marketing, beckoning the world’s leading designers to redefine the city's profile. From BIG to SOM, from Renzo Piano to Snøhetta and David Chipperfield, through epicentres such as the Scalo di Porta Romana, the CityLife and Porta Nuova areas, and the historic centre, Domus explores the building sites currently underway that are expected to be completed by 2025 and for the 2026 Winter Olympics. In the hope that the metamorphic mechanism underway will not leave behind parts of the society (as well as of the city) that are often marginalized by the implacable logics and strategies of markets.
