Estadio El Sadar (IV) – design description

“Rojo-Azul” means simply Red-Blue and that's the principle around the Vaillo + Irigaray Architects entry. El Sadar would be surrounded by brand new kinetic facade, which would change colours between red and blue depending on the beholder's movement. Contrary to common practice, the coloured perforated mesh would not be the most exposed external element, rather providing background to a strong diagonal frame.

The created form is simple, unified, rhythmic and disciplined. It's also visually lightweight as it extends beyond the auditorium itself and hovers above the plaza below. This way shade and rain protection is created among fans gathering for games, while above ground level there's room for quite some additional floor space, to be used on matchdays and beyond.

Inside the stadium atmosphere plays crucial role. With 24,000 people inside the stadium should be intimidating to opposition players. Already the old lower tier provides rake of 35º, which means that overhanging additional seats would be even more inclined, at 39º. Low-hanging roof would amplify the sound which, with entirely enclosed seating, should be kept inside the stadium.
