La Seine Musicale


Innovation and Sustainability Werey Stenger Plâtre & Staff

La Seine Musicale, designed by Shigeru Ban and Jean de Gastines, was thought in respect of the site and its industrial past. Its curves follow the shape of the downstream tip of the island. Its ambition is to be part of an eco-responsable future. The Auditorium with an audience capacity up to 1150 people, is the room dedicated to non-amplified music. Its acoustic was studied by Nagata and Jean Paul Lamoureux to guarantee the best possible sound reproduction for the audience.

Key Achievements

  • The team work: response to technical challenges
  • Innovation with the setting up of an ATEX
  • Optimising the truck transportations in order to reduce gas emissions
  • The dimensions of ceiling parts were created with the hard manipulation in mind for the workers

Key Challenges

First auditorium to work without any sound system. Laboratory endorsement before the setting up. Very precise finishing work especially for the movable walkways. Almost zero waste on site
