Perched high above Central Park on the 15th floor of one of Carnegie Hill's most distinguished prewar cooperatives, Residence 15A at 1170 Fifth Avenue offers an exceptional blend of timeless architecture, refined modern living, and breathtaking park views. Originally designed in 1925 by renowned architect J.E.R. Carpenter, this impeccably renovated corner home spans approximately 2,225 square feet and has been thoughtfully reimagined with elegant custom finishes throughout. Bathed in natural light from multiple exposures, the residence enjoys spectacular direct views of Central Park from the west-facing living room, the library/second bedroom and bath, and the corner primary suite.

The sophisticated primary suite includes two walk-in closets, custom built-ins, and a beautifully appointed windowed marble bath. The second bedroom, currently configured as a library, also enjoys direct park views and classic herringbone flooring, while the third bedroom features an ensuite marble bath and an open northern exposure with a glimpse of the park. Designed for both entertaining and everyday comfort, the impressive corner Dining Room offers custom cabinetry, a wine refrigerator, and an additional window seat with an open Eastern exposure.
