Seating Towers for The Yard at Chicago Shakespeare Theater

Theater consultant Charcoal Blue envisioned the concept of seating that could be moved for the needs of the performance space – large end on, thrust, theater in the round, etc., and could be achieved within one building with seating that could be reconfigured.  This was only possible if they could meet the seating capacity requirements to make the show economically viable.  Thus, towers were necessary to provide enough seating for the performances, yet they had to be reconfigurable with the rest of the space.  Mr. Ipema worked with the set design company Show Canada to provide a structural system that met many constraints – height, weight, constructability, and design aesthetic, to name a few.  The result is a structure that is as critical to the show as the actors.
