“The building is cast-in-place concrete, its spiral shape formed by a grand cantilevered ramp, over one-quarter of a mile long, that curves unbroken from the ground to the heights of the dome, almost one hundred feet above. This circular form is repeated in the elevator shaft, the skylight and the auditorium below the main floor and in the decorative motives such as the circles of the terrazzo floor and the outside pavement, the grills, windows and even flower beds.”
“The ground floor provides a multipurpose space useful for the display of large paintings and sculptures and is ideal for special events. The High Gallery supplies additional space for sculpture and monumental pictures and is in marked contrast to the seventy-four niche-like bays that compose the primary display areas.”
“Adjacent to the exhibition wing, and linked to it by the Justin K Thannhauser galleries above and the new bookstore below, is the Administration building which houses the offices of the museum staff. It is circular in plan, with a light-well surrounding the utility core which extends from the ground to a skylight above” (9).
