The museum welcomes the mezzanine floor, known as the Project Rooms, in 2015 with a proposal for a venue that transforms it into a more holistic, more qualified exhibition space, or a fine-tuning of the space in question.
The light reinforcement of the Mezzanine, the office corridor and the areas at its two ends were arranged to display works of art of appropriate size and quality. Being a second space with an identity of 160 m² that can be opened to thematic exhibitions independently of the Periodical Exhibition Area on the ground floor of the Mezzanine Floor, it also ensures the increase of the Periodic Exhibition Area and the integration of the interior space for the museum.
