The old theatre was built by the architect Josep Goday in 1912, and it has been remodeled. The rest of the premises have been tidied up and cleaned of unnecessary structures, and the vertical communications have been reorganised.
The façade in Joan Coromines Square, opposite the Barcelona Museum of Contemporary Art (MACBA), is the set of arches preserved in one of the cloisters of the old hospital, the Casa de la Caritat.
The open passage between the theatre building and the old church of the hospital, which connects Valldonzella Street with Coromines Square, widens towards the square on the ground floor to organise a covered outdoor atrium that protects the new front door of the refurbished building. The two hollow arches on the cloister façade help to indicate this access.
In the interior trapezoidal space, between the façade of arches and the volume of the theatre, the lobbies have been organised which, by means of escalators, make it possible to communicate the exhibition and cultural levels. These lobbies also connect with the new passage under the square, which serves as an exhibition area and umbilical cord with the main building of the Centre for Contemporary Culture (CCCB).
The new roof of this space includes the south façade of the theatre and helps to merge it with that of the cloister.
New openings have been incorporated into the geometry of the arches of the protected façade, in which the letters CCCB can be more or less read, which allow views of the square from the inside through unexpected cuts.
