The building has been designed as a large, streamlined, sober and expressive shape that offers the solemnity that is in line with the use it houses, since this establishment is known as the Basque "Pelota" centre.
The programme is organised in such a way that the various uses are combined to ultimately comprise a large parallelepiped of pure geometry.
The resulting large black monolith represents a milestone in Bilbao's suburban landscape.
The interior is an open and connected space that varies from compressed transit areas to expanded recreational areas.
The building has been designed as an experience for spectators that goes beyond simply attending a sports event.
Users walk through an interior landscape that is full of visual connections and diagonal spaces; a porous interior that has few divisions but is able to segment the various areas.
The sober exterior is a contrast against the interior's geometric complexity caused by the position of the inclined planes that form the stands and the priority given to colour and natural light inside.
