As of August 2025

Available October 1st - Unfurnished. Access is permitted Monday through Thursday from 11:30 AM to 1:30 PM and 3:30 PM to 5:00 PM, and on weekends from 10:30 AM to 4:30 PM.

Opportunities like this are rare in this highly desirable Flatiron boutique condominium.

This expansive 2,260 SF loft offers two bedrooms plus a home office (easily a third bedroom) and three full baths, all framed by 10-foot ceilings, abundant southern light, and fresh, top-to-bottom renovations.

A key-locked elevator opens directly into an impressive gallery that flows into a vast living and dining area with four oversized windows overlooking 20th Street. The gas fireplace with stone surround sets the tone for elegant entertaining, while the dining area easily seats eight. The home is equipped with electric shades and a Control4 smart home system that manages Sonos audio, lighting and more.

Unique to this residence, the kitchen has been completely opened to the living space and is anchored by a generous center island with seating. Outfitted with sleek Scavolini cabinetry, stone countertops and backsplash by Porcelanosa, and a full suite of high-end appliances - Sub-Zero refrigerator, Wolf range and oven, a second Miele oven, Miele dishwasher, built-in Miele espresso maker, two wine refrigerators, and a Miele microwave - it's a dream for both cooking and entertaining.

The bedroom wing is arranged for maximum privacy. The king-sized primary suite boasts a custom walk-in closet and a spa-caliber five-piece bath with double vanity, Robern medicine cabinets with built-in outlets, a rainfall shower, heated floors, an air-jet soaking tub with built-in television, and a separate water closet. The second bedroom is serviced by a full bath with glass-enclosed shower. A spacious home office (or third bedroom), full-size shelved laundry room, dual-zone central HVAC, wide-plank hardwood floors, and recessed lighting complete the home.

The Building

Originally constructed in 1906 and fully redeveloped by Extell Development into a luxury condominium, 15 West 20th Street - also known as the Altair - combines the character and scale of a pre-war building with the infrastructure, finishes, and amenities of a modern high-end residence. The facade, as captured above, is a striking example of restored architectural grandeur, and the lobby has been fully renovated to reflect the building's elevated design standards. With only 17 residences, it offers a true boutique living experience. Amenities include a part-time door person, fully equipped gym, common landscaped roof deck with grill and shaded seating, and oversize cage storage for each apartment.

The Neighborhood:

Situated on a quiet block in the heart of Flatiron, you're moments from Madison Square Park, the iconic Flatiron Building, and culinary landmarks like Eataly and ABC Kitchen. The neighborhood has flourished with exciting additions such as Pura Vida, the Ritz-Carlton with its NuBeluz rooftop lounge (one of the hottest spots in the city), the Virgin Hotel, and the exclusive NoMad Members Club with Cecconi's restaurant. World-class shopping, cultural venues, and multiple subway lines are all within easy reach.
