The new indoor sports stadium for speed skating on an ice skating track 400 m long, the so-called "Oval" course, stands in the Lingotto area of Torino. A large new building, architecturally and technologically innovative, covers an area of over 200x100m and can accommodate around 8,000 spectators during the Olympic event. The metallic structure has the advantage of having a single span roof that, after the Olympic event, will easily become the natural finishing touch for the largest exhibition structure in Torino located in the old Fiat factory of Lingotto.
The building is composed of the main hall with an area of about 20,000 m2 where the 400m oval ice skating track is located, entrances with related services on the east side, service areas on the west side, and two large façades next to the south and north sides. The north façade towards Lingotto is completely in glass and partly curved creating a visual link between the building and the Lingotto factory. This is one of the most significant architectural elements of the intervention. The south and east sides will be opaque, with a lower transparent strip next to the exits. There are three buildings containing various functions rising on the east side oriented towards via Nizza where entrances are planned. Their purpose is to reinterpret the style of the nearby Lingotto building renovated by Renzo Piano. The side with the entrances was designed to be easily dividable in various sectors, both during the Olympic Games and for post-Olympic use as an exhibition hall. From the entrance hall, similar to a real foyer, you can go up to a long terrace from where there is a view of the entire main hall.
The main hall appears as a large easily adaptable area, which can be used both as an exhibition area and an ice sports venue. The roof is constructed with a crisscross metallic structure entirely visible from the inside, while from the outside it appears to have an extremely simple shape. The two wings emerging from the roof are due to the planned functional separation of the exhibition building.
