One of the critical provisions for the ADL was their need to accommodate large meetings for up to 200 persons. Unfortunately, the existing space presented many challenges: existing columns were spaced closely together, floor-to-floor heights were too low, and the concrete frame was difficult to modify. The logical solution for such an assembly space was a rooftop expansion. The expansion married a new steel structure to the existing concrete frame, clad in stucco-faced styrofoam panels in order to minimize the additional weight. The interior space became a new meeting room housing up to 225 people with a full kitchen, a storage area, a state-of-the-art multimedia system, a new handicapped-accessible elevator, and safe areas as the building had no sprinkler system.
