Description

Timeless Eight Room Classic at Astor Court

Set within the iconic Astor Court, this grand eight room residence offers three bedrooms, three full baths, and two separate home offices, capturing the scale and architectural integrity that define classic Upper West Side living.

Built in 1916 and thoughtfully updated for modern life, the home retains its prewar character while offering remarkable volume and flexibility. A gracious gallery foyer introduces a layout of exceptional proportions. Every principal room enjoys natural light from two exposures, with five rooms overlooking the building's private landscaped garden and three rooms facing West with open city views and warm afternoon light.

The living room is expansive and elegant, anchored by a decorative fireplace and wet bar, and framed by oversized windows overlooking the courtyard. Opposite, the formal dining room features classic plaster detailing and a wood burning fireplace, easily accommodating large scale entertaining or serving as an additional sitting area.

The windowed kitchen is generous and thoughtfully designed with custom cabinetry, marble countertops, pantry storage, Wolf, Viking, and Sub Zero appliances, dual dishwashers, and a full sized washer and vented gas dryer.

The bedroom wing is intelligently arranged for privacy. The primary suite offers excellent scale, two walk in closets, and a windowed bath with cast iron tub. Two additional bedrooms are well proportioned and served by sizable windowed baths. Two separate home office areas and abundant storage throughout enhance everyday functionality.

Designed by Charles A. Platt for Vincent Astor, Astor Court is a distinguished full service cooperative with entrances on West 89th and West 90th Streets. The building surrounds a beautifully landscaped courtyard and offers full time door staff, resident manager, landscaped roof terrace, fitness room, playroom, central laundry, bike storage, and on site garage.

Moments from Riverside Park, Central Park, the 1, 2, and 3 subway lines, and neighborhood shopping and dining.

Two percent flip tax paid by purchaser. Pets and pied a terre purchases permitted.
