Christian de Portzamparc, architect of the Champs Libres

The programme is composed of three institutions : the Brittany Museum, the Library, and the Science Centre. At the time of the invitation for proposals, in 1993, these institutions were very active in the city, were all well-established, but were independent.
The idea of Edmond Hervé (Mayor of Rennes and President of Rennes Métropole) of combining these three educational centres on the same site was excellent. It was to create a synergy, to mix the types of users, cultures, and knowledge in a stimulating way. However, it seemed to me carry a risk that individuals could lose themselves within it, fading away into a large bureaucratised container.

Faced with this programme, one rule : not to fuse the three buildings together

It was essential to the project that the three institutions should be immediately visible and distinguishable from the outside. In other words, it was important that they should not be all fused together in a single big box where there would be some floors belonging to the library, and other floors belonging to the museum and science centre. I thought that these institutions would like to be physically identifiable.



Materials firmly fixed in a region


In the original scale models, the whole of the building was white, but I wanted to differentiate the colours and materials of the three architectural component parts. However, I did not want to construct a UFO, a building without any connection with the city. It was the materials and colours visible in Rennes which thus helped to guide me with, first of all, the red schist which is so distinctive a feature throughout the department of Ille et Vilaine.

I wanted the great table, the dolmen of the Brittany Museum, to have the appearance of stone. I worked a lot with concrete, designing the relief on which we then worked with the sculptor, Martin Wallace, to produce a  scale model.

With the EPI company, we worked in a random fashion on different greyish-pink sands and aggregates. We worked from only two moulds which had tectonic plate-like traces of lines, faults, and fissures which cross the joints of the panels, and put them together along the whole of the wall, without ever repeating the pattern.
In the end, it cannot be seen that there are only two modules. Moreover, I had kept the idea that the Library would be in glass and white gloss-finished aluminium. Finally, we needed a material for the Science Centre that could cover both the cone and the sphere, and scales of dark grey zinc were the simplest solution.
