Description

Residence 17A is a half-floor, three-bedroom, three-bathroom home spanning 1,944 SF with 211 SF of irrigated, planted loggias. Floor-to-ceiling windows frame sweeping landmark views, while a gracious entry foyer opens to a bright, east-facing living and dining room. A full-length loggia extends from this space, creating a seamless indoor-outdoor connection. The custom kitchen pairs oak, lacquer, and ribbed-glass cabinetry with Calacatta Lincoln marble slabs and a suite of premier appliances including a Thermador six-burner range with vented hood, Bosch speed oven and dishwasher, and Gaggenau refrigeration and wine storage. The south-facing primary suite features a large walk-in closet and a five-fixture bath with heated marble floors, Kohler soaking tub, glass shower, Toto water closet, and Watermark bronze fittings. Two additional bedrooms enjoy southern and eastern exposures; one has direct loggia access and an ensuite limestone bath. A third bath features Gaudi marble and limestone accents. White oak wide-plank flooring, central air, washer/dryer, and abundant storage complete the residence. Flatiron House spans 23rd to 24th Streets with two towers connected by a lush garden and glass walkway. Amenities include an attended lobby, fitness center with terrace, residents’ lounge, game room, and landscaped gardens—all moments from Madison Square Park and the best of Chelsea and Flatiron.
