There will a new building with an entrance at the end of the agora and there was a need for a large number of people to be able to walk through the space now in contrast with a more diagonal circulation as up to now.

I have designed (seen below) for Seed & Helix at Société Générale’s central headquarters at la Defense in Paris. The inferior point of the sculpture and the water level is separated by just a few millimeters.  All the agora laterals and reception is a design by Christian de Portzamparc.
