251 West 91st Street Upper West Side Apartment For Sale

Only Two Residences Remain at The Westly. This is One of Them.

Now Selling. Immediate Occupancy. Private Rooftop Terrace. Iconic Skyline Views.

Perched atop The Westly, Penthouse B is a one-of-a-kind trophy residence offering timeless refinement, panoramic views, and the rare luxury of a sprawling private rooftop terrace. With only two homes remaining in this nearly sold-out Upper West Side landmark, this is a unique opportunity to own a modern architectural gem in a completed, move-in-ready building.

Experience 3,059 square feet of elevated living across four bedrooms and four-and-a-half baths, crowned by a dramatic 1,079 square foot private terrace that spans the Manhattan skyline from the Hudson River to the East Side. This is one of the most significant outdoor spaces available on the Upper West Side today.

Step inside to wide white oak herringbone flooring and an elegant entry foyer with a custom closet. The open-concept living and dining area is framed by southern and eastern exposures and anchored by a floor-to-ceiling, marble-clad glass fireplace — perfect for both everyday living and entertaining.

The windowed kitchen is a chef’s dream, featuring Crema Delicato marble countertops, matte lacquer cabinetry by Aster Cucine, and integrated Gaggenau appliances. The north- and east-facing primary suite includes two walk-in closets and a five-fixture en-suite bath finished with Calacatta Gold marble slab, mosaic accents, and a freestanding soaking tub by Waterworks.

Secondary bedrooms are equally refined with eastern light and richly appointed baths. A gracious powder room features Calacatta Gold marble flooring and accent walls. The full-size laundry room includes side-by-side washer and dryer.

Designed by award-winning ODA, The Westly brings a bold cantilevered presence to the classic Upper West Side streetscape. This is modern architecture with warmth, balance, and soul. Residents enjoy 20,000+ square feet of lifestyle amenities, including:
• 24-hour concierge
