The Osborne is one of the great pre-war cooperatives on West 57th Street, AKA “Billionaire's Row”. All the right “bones” exist to customize an exceptional layout for a unique one-of-a-kind full time home or pied-a-terre. Need more space? Adjacent is a 2-3 bedroom duplex terraced penthouse with private outdoor space. (See listing for 11/12A). Enjoy exciting open city views and watch the ball drop on New Year's Eve from the Osborne roof! The Osborne, like the Dakota, is one of the finest examples of turn of the century architecture in Manhattan. With an unparalleled location across from Carnegie Hall, around the corner from Central Park at the crossroads of everything happening in town, the landmarked Osborne is a rare surviving example of the 1880's gilded-age famous for its elaborate entrance and richly appointed lobby. Built for the prominent citizens of the day, and home to countless luminaries over the years, the Osborne retains its elegant and important history. Pet and pied-a-terre friendly.
