The Luxembourg State decided to take the orchestra over and place it in the responsibility of an establishment specially created for this purpose, the Henri Pensis Foundation.

In 1997, Christian de Portzamparc's project was selected at the end of the international architectural competition launched by the Administration for Public Buildings.

The acoustic design of the three halls is the work of Chinese-born acoustician Albert Yaying Xu with AVEL Acoustique [Jean-Paul Lamoureux et Jérôme Falala].

To overcome the constraints of a rectangular room and to optimize the acoustics, eight towers of boxes are located around the stalls in an irregular fashion and contribute to uniform sound distribution.

Situated in the basement of the Philharmonie, the Espace Découverte (Discovery Space) stands out with its technical equipment and great versatility, and seats up to 180 people.

This space is used for experimental and electronic music, projects in the fields of film, art or video, for workshops, and for a large number of concerts and performances for children and young people.

The administrative structure of the Philharmonie is outlined in the 21 November 2002 law relating to the construction of a public establishment named Salle de Concerts Grande-Duchesse Joséphine-Charlotte.

[2] Since its opening, the Philharmonie has been the home of the Luxembourg Philharmonic Orchestra in permanent residence, of which Gustavo Gimeno has been its music director and conductor since 2015.

A large part of the programme also revolves around public concerts for the young, with different series of shows adapted to each age group, given in several languages.
