A main objective of the competition proposal was to give the stadium a public entrance, kind of a lobby towards the city. The existing stadium had 57 doors but not a main entrance. On the Castellana side, east facade, the plaza was levelled in order to generate a main entrance to the stadium beneath the new facade's large overhang.
Although the new envelope is shaped freely, its geometry is not accidental. The curved volumes are able to reflect light in a changing way, its marked lines expressing energy and drive.
While visually dominating its surroundings, the stadium volume is adapted to the program behind it, swelling or shrinking without losing unity or character.
The ventilated cladding material is designed to allow or to block sunlight through its changing pattern. The skin geometry is line-based, which allows a building process that -despite its high-tech component- is relatively simple and allows for large sections to be shop-assembled.
The reflective quality of steel together with the surface treatment creates this diffuse reflective quality over the façade. Together with the curve and its sinuous forms, the façade dematerialises which helps to reduce its apparent volume and better integrate with its setting.
