Description

This full-floor 4 bedroom residence spans 3,194 square feet and embodies the refined, nature-inspired design of COOKFOX Architects. Offered as a resale, it presents a unique opportunity to acquire one of the building’s most sought-after layouts, complete with 222 square feet of planted, irrigated outdoor loggias. A private elevator opens directly into a gracious entry gallery, leading to a dramatic corner living and dining room framed by floor-to-ceiling windows with sweeping 360-degree views. The corner kitchen, surrounded by four oversized windows, is beautifully appointed with custom oak, lacquer, and ribbed glass cabinetry with brass detailing, Calacatta Lincoln marble counters and backsplashes, a large island, and a pantry, alongside a suite of premium appliances.

The residence features four well-proportioned bedrooms and four luxurious bathrooms, including a serene corner primary suite positioned along the east and north exposures. This private retreat is complete with a large walk-in closet, windowed dressing room, and a five-fixture spa bath outfitted with a custom vanity, heated marble floors, a six-foot Kohler soaking tub, glass-enclosed shower, and separate water closet. Additional bedrooms and bathrooms are equally refined with Watermark oil-rubbed bronze fittings and elevated finishes throughout. Additional in-unit features include custom automated shades, bespoke millwork and built-ins, central heating and cooling, a dedicated laundry room with vented dryer, refuse closet, and abundant storage. The home is available to be purchased furnished. Note: Some photos have been virtually staged for illustrative purposes only.

Spanning 23rd to 24th Street, Flatiron House is comprised of two architecturally distinct buildings connected by a lush planted garden and glass walkway, offering a suite of amenities designed by COOKFOX. Residents enjoy an attended lobby, a fitness center with terrace, landscaped gardens, a residents’ lounge, and a game room. Ideally positioned at the crossroads of Chelsea and Flatiron, and just moments from Madison Square Park, the location provides effortless access to some of Manhattan’s finest dining, shopping, cultural institutions, and transportation
