When it was announced that Bertrand Goldberg’s iconic Prentice Woman’s Hospital was to be demolished, the Chicago Architectural Club, AIA Chicago, and the Chicago Architecture Foundation jointly held an ideas competition to explore alternate uses for the building. We proposed using the historic structure as a base for a vast programmatic expansion that included a new downtown YMCA. Given the dimensional requirements of athletic facilities, the added functions of the Prentice Y were stacked vertically. The design took advantage of the unique views and spatial opportunities that resulted from the unusual elevated location of these activities.
