The ballroom is the largest public space in the Lafayette. This space was added during the 1916-1917 addition. The ballroom is long, and is unobstructed by any columns because there are no rooms above it. The ceiling has large beams supported by pilasters along the side walls.
At one end of the room is a curved stage area. This curved area was added during another renovation in 1924-26. Behind the stage is an actors green room area, stairs to the upper floors and basement, and conveyer that tool dishes into the basement.
There were three small windows boarded up which have now been reopened to their original size.
Damage to the ceiling was extensive. The plaster beams were removed, the damaged ones replaced, and a new system was put in place to support the new beams and ceiling.
Unlike the floors in other areas of the hotel, the floor in the ballroom is wooden. One speculation is that when this addition was built, the owners could not afford a tile floor and used the cheaper covering of hardwood.
