The formalization of this concept is based on the concrete, which through its plasticity, allows to create irregular and free-form shapes, working both as a structural solution and exterior appearence, creating a unique shape, a monolithic building, bringing cohesion and unity to the set.
The technical complexity of the building leads to a periphery structural solution, a shell of concrete, like an egg, reducing internal support to the two stairwells and three central pillars, allowing great versatility in its interior space use.
Functionally, the building has eight floors working three as underground. On the ground floor, in addition to the auditorium, we have a store facing the Boavista Avenue, the cafeteria and office acess.
