39 W 23Rd St

Flatiron House is a contemporary, mid-rise residential development completed in 2022 and rising 24 stories across two connected volumes. Conceived by COOKFOX Architects, the project links separate buildings with a planted central garden and an architectural glass walkway, creating a campus-like feel between 23rd and 24th Streets. Interiors emphasize high-end residential finishes: wide-plank white oak floors, floor-to-ceiling windows, high ceilings, private elevator entries for select full- and half-floor homes, expansive walk-in closets, and kitchens with custom oak, lacquer and ribbed glass cabinetry framed in brass and Calacatta Lincoln marble countertops. Bathroom specifications repeatedly include heated marble floors, double vanities, Watermark oil-rubbed bronze fixtures, Toto water closets, soaking tubs and glass-enclosed showers. Common amenities, also designed by COOKFOX, include an attended lobby, residents’ lounge, fitness center with an adjacent terrace, game room, and planted roof/terrace spaces; many residences have private outdoor loggias or Juliet balconies, and some penthouses feature irrigated planted balconies. The building offers elevator service, central heating and cooling, in-unit laundry or dedicated laundry rooms, generous storage and smoke-free residences. Located half a block from Madison Square Park at the Chelsea/Flatiron crossroads, the property provides immediate access to dining, galleries, and transit while presenting a planted, garden-forward approach to urban condo living.
