Flatiron House is a contemporary, low-slung residential compound completed in 2022 that occupies two conjoined buildings rising roughly 24 stories with a total of 45 residences. Conceived by COOKFOX Architects, the development pairs brick-and-glass massing with planted loggias and full-height windows to emphasize light, views, and a connection to greenery. Unit types skew toward larger homes — one- to four-bedroom layouts including half-, full- and multi-floor residences and duplex penthouses — many with direct elevator entry and high ceilings. Interiors are finished with wide-plank white oak floors, custom millwork, eat-in chef kitchens with Calacatta marble counters and high-end appliances, generous walk-in closets, laundry rooms, and heated marble primary baths. Outdoor options range from Juliet and planted loggia balconies to substantial private terraces and a private roof terrace on the penthouse; several homes feature planted and irrigated loggias that run the length of facades. Shared amenities are garden-focused: a central planted garden linking the two buildings, an attended lobby, residents’ lounge and game room, a fitness center with an adjoining terrace, bike storage, supplemental laundry and optional private storage and parking. The building sits at the Chelsea/Flatiron crossroads, a half-block from Madison Square Park and within easy walking distance of restaurants, transit, galleries and cultural destinations, offering an urban lifestyle that balances quiet planted spaces with direct city access.
