Flatiron House

Flatiron, New York

39 W 23rd St, New York, NY 10010, USA

The first thing you notice about this boutique collection of condominiums, situated steps from the Flatiron Building and Madison Square Park, isn’t its location—and that’s saying a lot. What really sets Flatiron House apart is its foliage-covered facade, designed by Brooklyn-based Future Green Studio in collaboration with COOKFOX Architects. Loggias are filled with lavender and thyme, and balconies burst with blueberries and alpine strawberries. The effect is visually stunning, and it’s also essential to the overall ethos, which prioritizes biophilic and sustainable design. From the living wall-like exterior to the lush central garden and floor-to-ceiling windows that flood interiors with light, nature is a clear focus. After all, explains Rick Cook, a founding partner at COOKFOX, “People feel better when they’re connected to nature.”

COOKFOX is known for environmentally responsive architecture and for reimagining the interface between urban buildings and nature—and Flatiron House is a perfect expression of this synthesis. It has a limestone-and-terracotta facade accented by cascading greenery, and its two buildings—the grid-like Tower (which cheats its narrow footprint with stacked massing) and the more understated Loft—connect via a serene interior garden. The development’s location, amid so many architecturally significant buildings, also influenced the design, which feels decidedly contemporary while also nodding to some of the historical details of nearby landmarks.

Named for its famous triangular building, Flatiron offers easy access to Midtown’s office buildings and Union Square’s shops and Greenmarket, but the neighborhood isn’t just a base for exploring others. Flatiron also has its own rich mix of outdoor space in Madison Square Park, dining options in Eataly and Eleven Madison Park, and historic architecture within the Ladies’ Mile Historic District.

Between them, the Tower and the Loft house 44 retreat-like residences, ranging in size from one bedroom to five bedrooms. All have lofty ceilings, generous layouts, and oversized windows; many have balconies, loggias, or terraces with self-irrigating gardens planted with edible herbs and berries. Interiors are elegant but warm—think Calacatta slab countertops and Gaggenau appliances in the kitchens and Arabescato marble and walnut vanities in the master bathrooms—especially in the two-story Townhouse, where a fireplace holds court in the center of the great room. The crown jewel, however, is the Penthouse, which has a private roof terrace, outdoor kitchen, and breakfast balcony. 

Flatiron House checks all the right boxes in terms of amenity spaces: the Lounge and the Game Room offer space for gatherings over games, movies, and food; the Garden is a serene, green refuge; and the Gym has areas for cardio, weight training, yoga, and stretching. The true highlights, however, are more subtle. The windows, for example, are designed to let light in and keep noise out. “Part of the definition of luxury and comfort and quality is also quiet,” says Rick Cook. “So the windows and window assembly are designed to perform at a very high level.” Another thoughtful detail? In addition to the full-time attended lobby on 23rd Street, there’s also a more discreet entrance on 24th Street.
