A unique Flatiron/ Chelsea full-floor luxury loft now at an unbeatable value at $5.75M, down from $6.75M! At under $1,250 per sq. ft, this is the cheapest unit of its kind in the area!
This 4,713 sq. ft. architectural masterpiece by Phil Olson offers an extraordinary canvas for customization. Featuring 4 oversized bedrooms, 3 bathrooms, a media room, home office, and ample storage, this expansive loft boasts soaring 12-foot+ ceilings, reclaimed pine curved walls, a stunning copper-walled office, and backlit Kalwall sliding doors. The mahogany-enclosed infinity tub and two-person steam shower in the primary suite add to its unique character.
While the space is packed with architectural charm and statement features, it does require some updating offering the perfect opportunity to reimagine and modernize to your taste. With its open-concept layout, maple hardwood floors, custom metal art deco front doors, and recessed lighting, the foundation is already set for a truly spectacular transformation.
Set in an intimate 11-unit boutique condo in the heart of Flatiron, just steps from Madison Square Park, Union Square, Eataly, Whole Foods, Trader Joe, top dining, and multiple transit options, this location offers both vibrancy and exclusivity.
