Perched at the iconic intersection of Park Avenue South and 18th Street, this sprawling corner residence represents the pinnacle of authentic Manhattan loft living, offered for the first time in over four decades. Positioned at the vibrant crossroads of Gramercy and Flatiron, the home is enveloped by nearly eighty linear feet of continuous window walls, where nine oversized windows bathe the space in natural light and frame dynamic architectural views. Currently configured as a palatial, wide-open layout with two full bathrooms, this massive corner footprint is a rare "white canvas" opportunity perfectly suited for effortless customization. The space easily and seamlessly converts into a grand two-bedroom configuration with the addition of a single wall, maintaining an expansive, airy flow while preserving the dramatic 11.5-foot ceilings and original restored maple hardwood floors. For those seeking maximum scale, the residence also possesses the rare plumbing and structural capacity to be completely converted into a masterfully designed three-bedroom, three-bathroom configuration (please refer to the alternate 3-bedroom floor plan for layout possibilities). Offering a remarkable equity-building opportunity, the residence is priced to allow a visionary buyer room to customize and upgrade. The cooperative provides a clear, board-approval path for premium infrastructure enhancements that can be executed during renovation, including the installation of central air conditioning and the replacement of the perimeter windows. With apartments in the building commanding north of $1,800 per square foot even in unrenovated condition, Unit 7B represents an uncommonly high-value asset with substantial built-in upside. Residents of this meticulously maintained boutique cooperative enjoy a suite of rare conveniences, from dedicated storage and complimentary laundry on every floor to a beautifully landscaped and furnished common roof terrace. Low maintenance, no active assessments, and a progressive board that welcomes pied-à-terre, LLC, and trust ownership make this one of the most stable and coveted real estate foundations in the neighborhood.
