Follow Along with the Powell Hall Expansion and Renovation

Powell Hall is one of America’s most acoustically renowned and visually stunning concert halls—and home to your St. Louis Symphony Orchestra. We’re renovating and expanding the 98-year-old building to preserve and enhance our civic treasure for generations to come.

This project is inspired by you: our goal is to provide greater access to music, an even more welcoming and comfortable experience for all, and a creative hub that helps us build connections through the power of music.

The revitalized Powell Hall will open in 2025 to coincide with the building’s centennial. We look forward to celebrating with you.

April 5, 2024

Part of the expansion and renovation of Powell Hall, the St. Louis Symphony Orchestra’s home, includes infrastructure changes. Recently, new cooling towers were lifted onto the roof of the backstage addition. These cooling towers will help regulate the temperature of the building, creating a comfortable space for audiences and artists.

Previously located near the concert hall, the design of the expansion moved the cooling towers and other mechanical systems to the expansion to reduce ambient noise in the auditorium and better organize infrastructure equipment in one area.

New cooling towers is one of many infrastructure updates in the expansion renovation of Powell Hall. The fire protection system will be expanded, new electrical and HVAC will be added, and plumbing enhancements are among other upgrades focused on making the concert experience safe, accessible, and welcoming for all.
