The apartment was rebuilt to create an elegant Classical foyer that would permit circulation to all major rooms, including the dining room, living room and master bedroom suite. A new kitchen was created off the dining room. The master bedroom suite was formed by demolishing the former servants area, and features his and hers bathrooms, study, and clothes storage, in addition to the master bedroom.

The principal feature of the apartment, however, is a luxurious library accessed from the living room. The library is approached through French doors and is designed to permit a variety of sitting, reading and study areas for the enjoyment of the collection, which numbers approximately 5,000 volumes. The library contains at its center a small study area designed for maximum privacy. In this "studiolo" one is completely separated from the rest of the apartment and surrounded by the calming ambiance of fine books and warm mahogany casework

The overall style of the apartment is Classical, in keeping with the contents of the library collection. However, a number of expressions of the Classical are drawn together within the apartment for variety and to give different personalities to individual rooms.

The pale blue dining room juxtaposes delicate Georgian panelling and display niches with more robust Gustav Stickley furnishings in quartersawn oak, including several fine antique pieces. The ecru living room is intended to bring in the most light possible from the North and to capture views of the East River. Furnishings in the living room are designed around a crisp palette of blue and yellow with fabrics from Christopher Highland.

The lightness of the living room contrasts with the richness of the mahogany woodwork in the library, which is accented with glowing alabaster light fixtures and polished brass hardware. Rich oriental carpets compliment the library interior, whose walls are completely lined in lead to reduce the sounds of the outside world to no more than a muffled softness: the ultimate luxury in Manhattan.
