This duplex penthouse spans the entire top floor of a landmark apartment building on Central Park West. The existing warren of small rooms was gutted to enhance city views and provide access to a 100-foot-long terrace overlooking the park. A loft-like volume comprised of the living and dining rooms opens off the kitchen and features dramatic views of the Manhattan skyline to the south and Central Park to the west. Walnut paneling, Cipollino marble slabs and White Oak flooring bring a refined, luxurious ambience to the open plan. The apartment has a total of six en-suite bedrooms on two levels.
