Renovated LOFT Condo in the heart of Flatiron.

Experience luxury in the form of privacy in this rare Downtown LOFT. Living at 15 West 20th Street, 9A, you are perfectly positioned at the crossroads of Flatiron, Chelsea, and NoMad, within a meticulously well kept condo. The structure encompasses pre-war history with modern renovations, sophistication, and the architecture often present in Tribeca.

Enter through your home through a private keyed elevator, the kitchen spills into a sun-filled great room with soaring ceilings, wide-plank hardwood floors, and oversized south-facing windows. The expansive dining/living room features a Heatglow gas fireplace and a built-in Sonos sound system, creating the perfect setting for both entertaining and everyday living. Southern facing light pours into the home through four tall windows. There is a versatile interior room that serves as a convertible third “anything” room, such as a studio, wine cellar, home office, library, or secondary den space. This third bonus room has central heating and cooling ducts and can be opened using transparent sliding glass doors if desired.

The kitchen is fit for a chef, it’s a showstopper - with new renovation such as a white marble waterfall island, custom shaker cabinetry, top of the line appliances including a Miele gas range, wall oven, built-in coffee system, Sub-Zero refrigerator, wine cooler, Kraus fixtures and even a pot filler over the stove. Also important to note, the oven vents out, allowing for the smells of cooking to move out of your main living space.
Two serene north facing bedrooms are each designed with luxury en-suite bathrooms, adorned with marble tile, Kohler fixtures, and Toto toilets. Because 9A is situated on a very top floor of the building, the bedrooms have views of the sky and better light than any other position in the building. The primary bedroom suite offers a five-piece bath with soaking tub, glass-enclosed shower, double vanity, and water closet. A third full bathroom with a standing shower, a discreet laundry room with Miele washer/dryer, and a two-zone central A/C system complete this thoughtfully designed home. Both bathroom vanities were refinished, and the primary bathroom stone was recently freshly polished and sealed.

Built in 1906 and redeveloped by Extell Development, 15 West 20th Street — known as The Altair Condominium — is an exclusive boutique building with only 17 residences. The 11-story structure boasts a two-story rusticated limestone base, beige-brick exterior, and ornate limestone bandcourses above the second and sixth floors. A distinctive dentillated cornice crowns the building, enhancing its historic appeal. Amenities include a door person from 9:00am-5:00pm every day, fitness center, landscaped rooftop with a built in herb garden and BBQ, plus 9A specifically comes with a private storage unit.

Located on a tranquil block in the Flatiron District, residents are moments from Madison Square Park, Eataly, ABC Kitchen, Union Square Greenmarket, and Fifth Avenue shopping. West 20th Street and 5th Avenue are main shopping corridors, once known as Ladies Mile Historic District. With multiple subway lines nearby, this is downtown NYC living at its finest — offering privacy, convenience, and timeless style.
