The spaces of the old ateliers offer very different microclimatic conditions. The ground floor were the spaces that Picasso used as ateliers, whereas the first floor has smaller spaces that were used as storage. Contrary to what was asked, the team opted to leave the ground floor as is, to preserve its spirit and avoid covering the walls where Picasso´s signature and drawings are visible. Exhibitions in these spaces will only happen during summertime as these should only host art pieces that can be exposed to light and the weather. If these were to be used as exhibition spaces all year round, they would either use far too much energy to be conditioned or they would have to be completely insulated to maintain acceptable conditions. The first floor will be renovated punctually, and will be conditioned to host exhibitions all year round. To host different types of art pieces, different conditions are required, and the space can be adapted to that. To prevent art pieces from degrading, they should receive only a limited amount of light (cumulated lux) a year. This amount depends on the materiality of the piece and can be classified in “over-illumination for sensitive objects”, or acceptable for “low”, “medium”, or “high” sensitive objects.

"The spaces on the ground floor are perhaps the most emblematic of the building, bearing witness to Pablo Picasso's work and the use he made of the place. However, carrying out work to make their climate controllable would involve numerous changes and would alter their appearance. With the aim of preserving Pablo Picasso's use of the space, preserving the appearance of the rooms, and drawing inspiration from exhibitions already held, we imagined assigning specific exhibition characteristics to the spaces on the ground floor. We believe that these spaces could be used as they are today, by adapting the works on display to the constraints of these rooms:

• The series of alcoves is accessible from the outside and no major changes are made to the exhibition rooms.
• Natural light is provided by the large openings in the façade.
• As in previous exhibitions, the works on display are in the open air. Only works that can be exhibited in the open air can be displayed in these alcoves.
  The exhibition spaces on the first floor have a controlled climate, so that they can be exhibited all year round: the existing insulation will be maintained, the floor will be renovated where necessary, and heating, electricity and lighting systems will be installed."
