Alumni Hall
Pittsburgh PA

Originally built by Andrew Carnegie as an art gallery, CMU's Alumni Hall was plagued with acoustical problems. The solution required striking a delicate balance between modern acoustic design and honoring the room's historic heritage. Sound-dispersing maple shells complement the restored hardwood floors, while a skylight constructed of lexan pyramids retains original room day lighting and eliminates harsh echoes. The new stage floor features a herringbone pattern that matches the original floor pattern.

In 2003, Alumni Hall received the Historic Preservation Award from the City of Pittsburgh's Historic Review Commission.
