The San Siro stadium in Milan is the subject of a massive redevelopment project and simultaneous legal disputes. The proposed transformation, driven by Inter and Milan, is estimated to cost approximately 2.302 billion euros. The plan involves demolishing most of the current Giuseppe Meazza site to construct a new 71,500-seat arena designed by Foster + Partners and Manica Architecture. This development includes a new tertiary district with office spaces, hotels, restaurants, and a shared museum, alongside significant urban infrastructure and green spaces.

However, the sale of the stadium by the Municipality of Milan faces a legal challenge seeking to declare the deed null and void. The lawsuit alleges the sale was rushed to avoid architectural protections, noting the transaction was completed on November 5, 2025, just five days before the stadium’s second tier would have reached the 70-year age threshold required for mandatory cultural heritage verification under the Cultural Heritage Code. While no seizure or construction prohibition is currently in place, the litigation introduces uncertainty for the owners, Stadio San Siro spa, regarding future renovations and construction.

As demolition planning progresses, Inter Milan and AC Milan are considering a proposal to allow season-ticket holders to purchase or receive free seats as mementos. This initiative aims to salvage approximately 80% of the 75,817 seats—roughly 60,654 units—to prevent approximately 273 tonnes of plastic waste, supporting circular economy principles. The distribution would occur during controlled sessions before a complex, four-phase demolition process begins. This demolition, estimated to cost 127 million euros, will include a ‘strip-out’ phase for mechanical systems, the removal of the steel roof, and the dismantling of stands and towers, an operation expected to last 18 months once the new stadium is operational.
