Snohetta has revealed plans for a major extension to St. Louis’s Powell Hall, creating a contemporary addition that expands the historic concert venue. The design introduces new entry points, expanded lobby space, and improved circulation, blending modern architecture with the hall’s original character. By carefully balancing contrast and continuity, the project enhances functionality while preserving the building’s cultural presence.
A glass atrium links the historic structure with the new wing, bringing daylight deep into the interiors and framing views across the site. Inside, rehearsal rooms, galleries, and public amenities are organized with attention to acoustics and spatial flow. Materials such as stone, glass, and timber reinforce ties to the existing hall while introducing a modern sensibility. The expansion positions Powell Hall to serve future generations, enriching both the visitor experience and its role as a cultural landmark in the city.
