  • Description
  • The combination of the 2nd and 3rd floors to create a sprawling 7,000 sq. ft. duplex—one of the largest Flatiron condo lofts available. Each floor boasts an expansive open layout measuring over 40 feet wide and 82 feet deep, with soaring ceilings ranging from 12.5 to 13.5 feet. This extraordinary space offers the opportunity to design a duplex of epic proportions. Imagine crafting a spacious 7-bedroom home with 7-8 bathrooms, generous entertaining areas, a media room, library, home office, gym, spa, ample storage, staff rooms, and more. The south-facing, oversized windows flood the space with brilliant natural light throughout the day. The current floor plans (both floors feature identical layouts) showcase a versatile blank canvas, and a proposed 7-bedroom configuration is also available for inspiration. With only two small columns on each floor, the possibilities for customization are virtually limitless. This exclusive boutique condo building comprises just 11 full-floor residences and features a doorman for added convenience. The seamless conversion from commercial to residential use provides the freedom to develop your vision. Nestled on a peaceful, picturesque block in the heart of Flatiron, this offering is a rare gem—a unique opportunity to craft an exceptional living space tailored to your style and imagination.
