Perched at tree level directly across from the park, this beautifully reimagined classic six blends the gracious proportions of pre-war architecture with a thoughtful, comprehensive renovation. Originally configured as three bedrooms, the home has been transformed into an expansive two-bedroom with library, while retaining the elegance, scale, and sense of formality befitting its Fifth Avenue address.

Arrive via a semi-private landing and enter through a gracious foyer wrapped in rich wood paneling, with sightlines into the formal dining and entertaining spaces beyond. The living room is anchored by a marble mantel surrounding a wood-burning fireplace, complemented by 19th-century gilt bronze sconces and a wall of triple-paned windows overlooking Central Park. Just beyond, the library offers a more intimate retreat with cerused oak paneling, custom built-in bookcases, and an ensuite bath, allowing it to function equally well as a den, office, or second bedroom.

The park-facing primary suite is serene and substantial, with upholstered walls, a custom-fitted closet, Doris Leslie Blau wool carpeting and a marble-clad ensuite bath with heated floors, soaking tub and separate walk-in shower. A second bedroom features hand-painted de Gournay wallpaper, wool carpeting, built-in storage, a large closet and convenient access to a semi-private guest bath.

The galley kitchen is finished with custom-built cabinetry, marble countertops and a full suite of Gaggenau, Miele and Sub-Zero appliances. Throughout the apartment, details include hand-cut herringbone oak floors, beamed ceilings, crown moldings, raised paneling, custom solid mahogany doors, zoned central air, humidification, triple-paned windows, custom lighting and fully updated electrical, plumbing and risers. An in-unit washer/dryer and private storage complete the home.

Designed by architect-developer Frederick Fillmore French and completed in 1922 in a restrained Renaissance style, 1140 Fifth Avenue remains one of Fifth Avenue's distinguished pre-war cooperatives. Residents enjoy attentive white-glove service from doormen, porters and a resident superintendent. The cooperative permits 60% financing and has a 2% flip tax payable by the buyer.
