La Seine Musicale

On the banks of the Seine in Boulogne-Billancourt, west of Paris, a ship-like building complex was built: “La Seine Musicale”. This cultural centre was designed by Shigeru Ban / Jean de Gastines and opened in spring 2017. The building envelope is supported by a free-form and geometrically networked glulam timber structure and has a rotating photovoltaic sail. The sail follows the course of the sun and, in this way, maximises energy production. In this architectural jewel, HESS TIMBER was responsible for the design, manufacture, and assembly of the free-formed glulam structure. The wooden structure extends to about 70 m in the longitudinal axis and about 45 m on the transverse axis at a height of 27.5 m. More than 1,700 unique timber elements (900 m³ of glulam) were delivered to the auditorium and assembled in about 10 months between September 2015 and June 2016. Cross laminated connection joints made from beech connects the wooden structure.

Started in July 2014, the building site progresses well. The structural work is finished and the glulam construction around the Auditorium is assembled. The works on the orchestra hall and the exercise rooms are still in progress. The building will be opened to visitors from 2017 under the Name "La Seine Musicale".

On the building site of Ile Seguin which formerly hosted the factory buildings of Renault Paris, a 36.500 sqm complex with space for 6.000 visitors is now being erected. Besides the cultural area, the building will also incorporate restaurants and living space for the musicians.


HESS TIMBER is very proud having the possibility to realize this Musical Center which consists  of two concert halls, recording studios and rehearsal rooms, together with the famous architects Shigeru Ban and Jean de Gastines who have a certain affinity to timber. "La Seine Musicale" is situated on the isle Seguin, a small island of the river Seine, and therefore necessitates very special assembly workflows.
