In some of the two-bedroom units, there is a foyer with a living/dining room, kitchens, and bedrooms leading off it. There are also duplex units with kitchens, living rooms, and dining rooms on the lower tier, as well as bedrooms on the upper tiers. One of the larger duplexes, on floors 65/66, has four bedrooms; a living/dining area with a library and breakfast area; a family room; and a terrace measuring 44 by 36 feet (13 by 11 m).[1] On upper floors, the units tend to be larger, reaching 2,200 square feet (200 m2) below the penthouse.[2]
