La Pampa is a huge flat natural territory as big as France. It has a large industrial and agricultural infrastructure and it is now inhabitated by more than seventy million cows. This Auditorium stands alone in the prairie, 33 kilometres from Santa Rosa. The shell is surrounded by an endless, plain space. A small park appears at the east. The building is formed by a semi-translucent bubble made of an aluminium curved net, partially covered by glossy zinc. The surfaces reflect the strong light that comes from Patagonia, at the very south of the World. The building contains four elements: the main Theatre, the stage area (partially open), a transitional area along the inner skin -transforming the passive act of hearing into the possibility of walking and listening- and the ground floor, which is a flexible space that links the entrance with the entertainment area at the top, where you can see the horizon from above... but not the end of it.
