39 West 23rd Street PHNew York, NY 10010

A rare full-floor penthouse perched atop Flatiron House, this masterfully designed residence by COOKFOX Architects offers 3,228 square feet of refined interior living and 916 square feet of private outdoor space, as well as a dedicated parking space with the ability to exit directly onto 24th Street. An elevator opens directly into the home, revealing a sun-filled open living and dining room with expansive south and east exposures and sweeping 360-degree landmark views framed by floor-to-ceiling windows. Iconic sightlines stretch from the Empire State Building and Flatiron Building to One World Trade Center, creating a dramatic backdrop throughout the home. The main living space flows seamlessly to a serene loggia with a private sauna, providing a tranquil retreat.

The corner chef’s kitchen is both elegant and functional, wrapped in four oversized windows facing south and west. Custom oak, lacquer, and ribbed glass cabinetry framed in brass pair beautifully with Calacatta Lincoln marble slab countertops and backsplashes, complemented by a generous island and pantry. High-end appliances include a Thermador six-burner gas range with griddle and double ovens, a vented hood, Bosch speed oven and dishwasher, and a Gaggenau refrigerator/freezer with a full-height wine refrigerator. A sculptural staircase ascends from the living area to the expansive private roof terrace, complete with an outdoor kitchen and ample space for dining, lounging, and entertaining against the city skyline.

The thoughtfully planned layout features three bedrooms and three-and-a-half baths. The northeast corner primary suite offers a large walk-in closet, a windowed dressing room, and a five-fixture bath with heated marble floors, a six-foot Kohler soaking tub, a glass-enclosed shower, a Toto water closet, and Watermark oil-rubbed bronze fittings. Secondary baths—one en suite—are finished with limestone floors, Ann Sacks textured ceramics, custom vanities, and Duravit fixtures. A full suite of COOKFOX-designed amenities includes an attended lobby, fitness center with terrace, lush planted garden, residents’ lounge, game room, bike storage, supplemental laundry, and private storage available for purchase. Ideally located at the crossroads of Chelsea and Flatiron, just half a block from Madison Square Park, this penthouse offers immediate access to the city’s best dining, culture, and transportation.
