Several sets of stairs raise the floor level of the passage as it progresses towards the rear of the building. Although one can enter the building at several locations on the left and right sides, one's eyes naturally focus on the lush garden behind the building and the large sculpture of a horse placed directly in the line of sight. The walls are covered with travertine and square deep-set windows are placed with geometric regularity. At the end of the passage the travertine disappears to reveal the steel structure beneath. The exposed steel frame extends rearward into the garden, merging with it as it provides a surface for vines to grow on.
Several bridges cross the passage on the third and fourth floors.
This quietly dramatic space is a strong contrast to the coolness of the facade and makes the visitor feel that he has entered a private world. A steel and glass cylindrical form with a domed roof lies at the center of the building. It houses the elevator shaft and a small lobby on each floor. The architect envisioned this as a modern form breaking through and rising out of the classically inspired stone and concrete sections of the building. When seen from the garden behind the building, the cylinder does indeed seem to be busting out of the building.
