Tinted glass was used for the middle floor, and clear glass was used on the top floor.

His dramatic conceptual scheme involves a sophisticated system of pedestrian pathways linking units of varying sizes, all clad in clear glass on the north and south sides and translucent glass on the east and west sides.
