The proposal for the new theater of Sta Perpetua de la Mogoda configures and generates the path to the institute, the entrance to the park and the public space that there is a side of the library. The building of the theater takes advantage of the existing overpasses to arrange an access to the hall. This one is on the same level that the stage and, thanks to the retractable stairs, it makes possible a wide variety of uses. The natural connection of the theatre building with the public space outside it enables the civic and performing activity convergence.
