Description

Grandly scaled living spaces combine with inspiring ceiling heights and light-filled interiors in this pristine 2,989sf corner loft at Flatiron's historic O'Neill Building, beautifully reimagined in 2007 by award-winning architectural firm CetraRuddy. The 3-bed, 3.5 bath residence is distinguished by its thoughtful layout and volume of space, including the dramatic 950sf turreted great room and elegant foyer where you are first introduced to the magnificence of this spectacular home. Illuminated by 28 oversized windows set against unique views of the cityscape to the north, east and west, the residence is remarkably livable with its oversized proportions and perfectly scaled entertaining spaces. The enormous great room offers three seating areas including a formal dining area just off the windowed, eat-in kitchen. Outfitted with premium Viking appliances and black granite counters, the chef's kitchen is adjacent to a large pantry and full-sized laundry room. Anchored by the foyer are the powder bath and two double storage closets. Wide-plank american walnut hardwoods and original cast iron columns warm the interiors and accentuate the architecture. The corner master suite is the ideal sanctuary with its gracious proportions, huge custom walk-in closet, city views to the north and west, and windowed, spa-like en suite bath featuring a soaking tub, separate shower, marble top dual vanity, and marble floors. Two additional bedrooms positioned against northern city views and with en suite baths complete this exquisite residence. Reimagined by award-winning architectural firm CetraRuddy in 2007, The O'Neil Building in vibrant Flatiron was originally built in 1887 and was the first block-long department store on New York's "Ladies Mile". With its striking domes and preserved architectural heritage, this 7-story boutique condominium conversion received unanimous approval from New York City?s Landmarks Preservation Commission and is comprised of 48 residential floor plans marked by inspiring volumes and grand scale. An intimate and fully-staffed building, residents enjoy exceptional amenities including a full-time doorman, a live-in super, and a 4000-square foot roof deck with an outdoor kitchen. Walking distance to Madison Square Park, and Union Square Park, this convenient location offers residents a sought-after lifestyle rich with New York's finest culinary experiences, shopping, and recreational activities.
