St. Louis Symphony Orchestra
A facility to nurture the creative process
Snøhetta is leading the design for the expansion and modernization of the St. Louis Symphony Orchestra’s historic performance space, Powell Hall. To ring in the performance hall’s centennial in 2025, the organization has embarked on an ambitious 65,000-square-foot expansion with Snøhetta as design architect and landscape architect. The project will allow the concert hall to be more fully accessible and open to the community, creating a facility that supports and nurtures the creative process from idea to performance.
At the renewed Powell Hall, a collection of new public spaces will work in concert with a new lobby and back-of-house expansion to provide universal accessibility to the public as well as educational facilities and improved musician and back-stage spaces that enhance overall community use of the concert hall.
Drawing on the spatial language of historic concert halls and the instruments within, the new entry is shaped as a series of canted shells assembled from raked masonry, creating a front-of-house addition defined by simple inclined surfaces and arched openings inspired by the musical nature of the historic building and its program. Inside, a suite of new gathering areas situated within a triple-height space will include terraces that overlook one another, allowing visitors to both see and be seen while attending performances.

Similarly inspired by the formal properties of instruments, and by the lyricism of music itself, Snøhetta is designing a new public plaza at the corner of Grand Boulevard and Samuel Shepard Drive that brings the activities of the concert hall outside. Replacing an existing parking lot, the plaza will provide a place for patrons to gather before and after performances, offering a platform for Grand Center where impromptu displays, informal gatherings, and other collective activities can augment the creative energy exuded by the concert hall. In other areas of the site, ample circulation and arrival zones will move people quickly to their destinations while also creating spaces that can be used as flexible programmed space if the symphony desires. A series of routes in and through the site will provide accessible pathways to patrons arriving from multiple directions, and planting groves will frame the entries, extending a sense of welcome and human-scaled experience that will greet visitors upon arrival.
Additionally, a back-of-house expansion along the eastern side of Powell Hall will bring new spaces for community events, educational programs, lectures, digital programming, and other collaborations while also serving as a hub for innovation across artistic disciplines. The expansion will also create new rehearsal spaces for SLSO ensembles, modernized and expanded backstage spaces, new media and recording suites, new dressing rooms, and new storage areas for musician and guest artist use. Ultimately, the expansion of Powell Hall will make the building a productive and inspiring venue for the musical and performing arts in St. Louis and beyond.
