A little off topic, but it involves a performance hall of the same era and architectural style. The NAC has maintained its original architecture and added a modern glass addition, continuing the geometric pattern of the original. It was supposed to be a centennial project, but was completed two years late in 1969.
The original architect was Fred Lebensold while the addition was designed by Diamond Schmitt.
The main entrance used to be Canal side, but a new entrance has been added on Elgin, facing the city. The Canal side entrance remains.

Some work has been done on the main performance hall, Southam Hall, to improve sound quality, including new seats with wooden backs. The overall design remains mostly unchanged.
Work on other theatres within the building has been planned. Not sure how far along they've come.
