The Flatiron Building is one of New York's most venerable landmarks — erected at the onset of steel-frame construction, when builders began to realize the city could expand upwards instead of just out. How our four- to six-story metropolis has grown since its 1902 completion — and continues to scale upward today. A half-block west of the icon at 39 West 23rd Street, a dignified new condo has squeezed its way into a through-block site in the historic Ladies' Mile district. Christened Flatiron House for its locale and views of the landmark, the first of the building's 44 homes have hit the market, bringing online one- to four-bedroom oversized condo residences that are said to provide a sense of warmth and well-being to residents.
Developed by Anbau and designed by the green-minded firm of COOKFOX Architects, Flatiron House imbues biophilic and sustainable design principles through numerous planted loggias (covered terraces), and a lushly-planted garden to be located between its two connected buildings. The south wing, facing 23rd Street, rises 25 stories, 278 feet tall, noticeably higher than most of its surrounding pre-war structures. However, since the district is defined by sawtooth streetscapes of buildings of varying heights and scales, the development avoids standing out as a mid-block sore thumb. It also helps that the building's east-facing walls have windows, which impart unique views of Madison Square Park and the Flatiron Building.

Flatiron House's rectilinear and structurally-robust design was approved by the Landmarks Preservation Commission way back in 2013. The commissioners were ambivalent about the pronounced east-facing cantilever but found redeeming qualities in its sculptural form and planted terraces. To better harmonize with the gorgeous masonry buildings of the Ladies’ Mile Historic District, the architects specified a gridded limestone and terracotta facade with bronze accents. Renderings show that the outdoor loggias will ultimately be planted with cascading foliage, which will provide a visual connection to Madison Square Park and bring in much-needed greenery to the concrete jungle.
Flatiron House's residences are airy, contemporary, and grand. Asking from $1.98 million, available one-bedrooms measure from 1,052 square feet and feature a powder room, en suite bath, and a large walk-in closet. Two-bedroom homes sprawl over 1,600 square feet and start at $3.375 million, while graciously-scaled three- and four-bedrooms are replete with outdoor spaces and start from $4.825 million.

With an overarching goal to promote health and wellness, all homes have filtered central air, acoustic mitigation, and finishes honed with natural materials. High ceilings and floor-to-ceiling windows will fill homes with natural light and many will have planted Juliet balconies that provide a tangible connection to nature and the cityscape beyond. Mid- and upper-floor homes will enjoy open views of the area which include the downtown skyline and the landmarks ringing Madison Square Park. A yet-to-be-listed penthouse will crown the structure, offering its lucky buyer direct elevator entry, a "breakfast balcony," and a private rooftop terrace with an outdoor kitchen.

  • Lofty ceilings
  • Oversized windows
  • White oak wide plank flooring (5.5" to 9.5")

Stretching between 15th and 24th streets between Park Avenue South and Sixth Avenue, The Ladies' Mile was the city's premier shopping district in the decades following the Civil War. The area was once anchored by the city's most renowned department stores and upscale retailers that include B. Altman, Arnold Constable, Bergdorf Goodman, Lord & Taylor, and Tiffany & Co. As the area attracted the wealthy and celebrities, it gained its reputation and name for being a safe area for women to shop and frolic without the accompaniment of men. Unaccompanied women with the potential to ogle exposed ankles and legs proved to be quite the public spectacle at the turn of the 19th century. Allegedly, the phrase 23 skidoo was coined around the Flatiron Builindg due to throngs of men waiting to see women's skirts blown up due to the updrafts caused by sheer form.

While no longer the epicenter of Manhattan shopping, as part of "Midtown South," the area remains one of the city's most important commercial districts, proving popular to technology and creative firms in recent years. The district was landmarked in 1989 and a large number of the former retail emporiums survive today — many of which have been adaptively reused into offices and residential apartments.
