In first level there are 3 boxes:
First is a box forming the entrances: towards the street and towards the plaza. It contains the underground parking access, the museum shop, public toilets, and the dressing room and podium for the theater.
Another box -aligned with the border- contains the art storage and the small café serving the plaza.
Third is a glazed box containing the box office and the access to Talleres de Robledo temporary galleries and the permanent galleries in the fourth level through the elevators.
There are 2 boxes in the second level. Both correspond to the museum offices which are covered by prefabricated concrete fretworks that allow ‘seeing without been seen’. This is the only level in the project that doesn’t have a direct access from public stairways since it for the museum only private use.
On third level there are 3 boxes:
A box contains the Sound Experiment Laboratory and 2 more laboratories for class and workshops given at the museum.
Another box -at the corner- hosts toilets and vertical circulation (2 public elevators, a service lift and emergency stairs).
Third box is the Theater seating 256 people. It can also be configured as an open theater with the city as a stage by opening its east façade, or even using the same stage but facing contiguous plaza for massive events as concerts.
In fourth level there are 2 boxes:
Both contain the 3 exhibition galleries for the museum permanent collection, each one complemented with an open space allowing exterior exhibitions or simply pauses in the trajectory to gaze the city.
In fifth level there is just one box, which is defined by metallic fretworks containing the space for the restaurant and events of the museum, profiting from the two large adjacent terraces.
