Foster + Partners and US studio Manica have unveiled the design for the Generali Stadium, the new 71,500-seater that will replace San Siro as the shared home of AC Milan and Inter.

To be built right next to the 99-year-old original (which will be knocked down once the new place is ready), the Generali Stadium is wrapped in a huge facade made of elongated, X-framed pre-cast concrete supports. It stands around 60 metres tall, holds up the seating bowl and the double-curved roof, and is built from low-carbon concrete segments joined by structural joints that are left on show.

Foster + Partners says it’s a nod to Italian engineering tradition, where the architecture and the structure are the same thing. The upper levels get a run of open, loggia-style spaces, framed by the facade and naturally ventilated.

Inside, the design starts with the curvas. The north and south stands face each other like two walls of supporters, with Inter behind one goal and Milan behind the other. Each end rises at a 37-degree pitch and holds 11,700 fans. Noise was treated as a design priority from the first sketches. The bowl’s geometry is shaped to amplify the crowd and keep the sound inside, so there’s less noise spilling out into the surrounding area.

On the green side, the stadium is planned to be all-electric and carbon-neutral in operation, with a LEED Gold target. The roof will carry 27,500 square metres of solar panels, and the pre-cast system should cut waste and speed up construction. It all sits within a 281,000 square metre masterplan with public space, greenery, leisure and retail.

The new ground is due to be finished in time for Euro 2032, which Italy co-hosts. The clubs will share San Siro until then, and it’ll be demolished afterwards. This is the second go at replacing it: the earlier Populous design, known as the Cathedral, was blocked in 2023 over the old stadium’s cultural significance. The sale that made demolition possible was only approved in October 2025, after a debate that ran for nearly 12 hours.

Foster + Partners is also working on Manchester United’s 100,000-seater, which has a giant tent-like structure, so the Generali Stadium is just one of two big football projects on its desk.
