La Seine Musicale was created to make culture accessible to as many people as possible. With this goal in mind, it was designed to serve as an intergenerational hotspot for wealth, exchange, and education as well as a wide range of activities.The building extends for 324 metres along the Seine River and covers 36,500 square metres. It includes two concert halls. La Grande Seine, which seats up to 6,000 people, is equipped to host concerts, ballets, major theatre productions, and company events. The Auditorium, which seats up to 1,150 people, is designed for acoustic musical performances. In addition to the arts-related infrastructure, adjacent amenities include shops and restaurants. La Seine Musicale also features a number of private rooms for hosting company events or public exhibits.

While the architects point to the solar cover lined with photovoltaic panels as the ultimate symbol of environmentally-friendly design in the 21st century, the entire building as a whole exists in symbiosis with its environment, especially with respect to its green roof.  The project's environmental commitments, which have been present since the very beginning, have been awarded several labels, including the Urban Biodiversity label. In addition, the complex was presented with the Sustainable Building HQE certification for its optimal air quality and use of premium materials.
