Given the lack of the surroundings definition, our proposal is an autonomous “object”, whose scale fits in the nearby surroundings, that are characterized by the presence of the stadium and some industrial buildings. We propose a simple large span hall, a parallelepipedic volume supported by a steel structure, which is covered both inside and outside with translucent white polycarbonate plates. Inside, three volumes define a central courtyard, where the tanks are. The volumes don't touch the ceiling, allowing a view of the whole space.
