Description

Refined Downtown LOFT Living. If you’re priced out of Tribeca, this apartment is in the cross roads of Flatiron, Chelsea, and NoMad - perfect connectivity to commute anywhere. Elevated by a private keyed elevator that opens directly into the residence, Unit 9A is a beautifully renovated home that seamlessly blends loft-like proportions with modern luxury. The home is exceptionally spacious with an interior room that can be used as a third “anything room” such as a home office, library, or guest room. Soaring high ceilings and oversized southern-facing windows flood the living room with natural light, highlighting the open layout, updated wide -plank hardwood floors throughout. A Heatglow gas fireplace provides a striking focal point in the living area, enhanced by a built-in Sonos sound system for immersive entertaining or everyday relaxation. The chef’s kitchen is a masterclass in both form and function, featuring a white marble waterfall island, custom wood-paneled shaker cabinetry, and a full suite of high-end appliances including a Miele gas range integrated into the counter, wall oven, built-in coffee system, dishwasher, and a Sub-Zero fridge and wine cooler. Kraus fixtures, an over-the-stove pot filler, and sleek finishes throughout underscore the kitchen’s utility and sophistication. As you walk down the hall, there is a full third bathroom with standing shower- perfect for guest use. Two tranquil bedrooms are wrapped in Schumacher textured wallpaper and have their own elegant marble-tiled bathrooms en-suite. Both are designed with polished chrome Kohler fixtures and Toto toilets. The primary bedroom has a five fixture bathroom inclusive of soaking tub, standing shower, double vanity sink, and water closet. Both bedrooms also face north with views of the sky, and quiet facades of adjacent buildings. A discreet laundry room is also tucked into the north side of the home. It features a Miele washer and dryer as well as ample custom shelving as storage. There is a two-zone central vented A/C system that ensures year-round comfort. Originally built in 1906, 15 West 20th Street underwent a full-scale luxury redevelopment by Extell Development. Reimagined as the Altair condo, this boutique building has only seventeen apartments. The building offers the privacy and scale of a classic pre-war structure, with the infrastructure and finishes of a modern high-end residence thanks to Extell’s touch. The result is a rare blend of character and quality in one of Manhattan’s most desirable neighborhoods. The building features a part-time door person, cage storage (included in the sale of 9A), indoor gym, and common rooftop. Located on a quiet block in the heart of the Flatiron District, the building is surrounded by some of the city’s best dining, shopping, and cultural experiences. Just moments from Eataly, ABC Kitchen, Union Square Greenmarket, and the boutiques of Fifth Avenue, residents enjoy unparalleled access to downtown living at its finest. With Madison Square Park just around the corner and multiple subway lines nearby, 15 West 20th Street offers the ultimate blend of historic charm and 21st-century convenience.
