9 E 88TH Street

Twenty-six feet wide, six stories tall, and set on one of Manhattan's most protected blocks, 9 East 88th Street is a rare Beaux-Arts mansion just off Fifth Avenue, with the Guggenheim nearby and Central Park at the end of the block. Built in 1902 by James R. Turner and William G. Killian, its interiors were later reimagined by John Russell Pope, architect of the Jefferson Memorial and National Gallery of Art.

Behind a rose-brick facade with limestone and marble detailing, the home opens to a dramatic reception hall with herringbone floors, a carved stone fireplace, and a sweeping wrought-iron staircase.

The parlor floor features a grand formal salon and an exceptional mahogany-paneled dining room with silk curtains, a carved marble fireplace, and leaded-glass windows. Above, the bowed library is lined in mahogany bookcases and opens to an iron balcony.

The dedicated kitchen floor is designed for full service, with a Viking range, double ovens, marble-topped island, prep sink, extensive cabinetry, and access to the rear stair and outdoor space. Three staircases and a wood-paneled elevator serve the home from basement to sixth floor.

Eight bedrooms and ten bathrooms occupy the upper levels, including a refined primary suite with bowed windows, marble fireplace, and a slab-marble bath with steam shower. Fireplaces appear throughout the residence.

At the top, a glass conservatory with vaulted skylight opens onto more than 1,500 square feet of planted rooftop terrace.

Approximately 14,125 square feet in total, the home also offers central air, updated mechanical and security systems, and irrigated terraces. Located within the Carnegie Hill Historic District, this is an extraordinary combination of scale, architecture, location, and history.
