The San Mamés Barria company was founded with the participation of the Athletic Club, Bilbao Bizkaia Kutxa Bank, Diputación Foral de Bizkaia, Vasque Country Government and the Bilbao City Council, in order to build the New San Mamés Stadium for the Athletic Club. The new Stadium has a total surface of 116.133 m² and 53,571 seats, as opposed to the former one (40,000).

The project juggled both the construction of the new Stadium and the normal functioning of the venue. The “horseshoe” was the first thing built and it didn’t interfere with the old structure. Season 2013-2014 was played in the unfinished new Stadium. In June 2013 the old San Mamés was demolished and the project ended with the construction of the last stand, the one that used to occupy part of the former stadium in August 2014

The addition of other areas for public use such as fitness and spinning areas, water areas, spa and swimming pool (50 × 10 m), athletics tracks, multipurpose gyms,changing rooms and a center for sport innovation are being considered.

The area above the ground is 69.524 m² distributed between ground floor and four other floors that support two grandstand, one for the general public and other intermediate boxes. In the underground area of 46,608 m², there are two basement floors and the first stand; this, due to the field’s design, remains a tad lower when compared with the elevated surrounding roads. The Stadium service equipment is located on the basement floors, along with changing rooms, referees’ room, service personnel, health and safety, medical facilities, press areas, storage and warehouses.

A garage with 270 car spaces, bus and heavy-duty vehicles areas is being projected.

The Athletic Club Museum, a restaurant, the Official Football Club Store, a Coffee shop, Multipurpose and Hospitality areas, a nursery and commercial spaces are also integrated in the project along with the whole perimeter urbanization of the complex.
