The resulting building remains the largest non-pillared auditorium in the Chicago area, and has permanent seating for 3,740 people, 2,270 on the main floor and 1,470 in the balcony. The curved balcony was one of the earliest examples of cantilevered construction, and its curvature – as well as the rest of the layout of the auditorium – was designed so that all lines focus on the pulpit. Designed in an era before modern sound systems, the building has almost-perfect acoustics, and it is reported that the only element detracting from this aspect is the floor carpet.
