Offered fully vacant immediately. Welcome to 137 West 80th Street… A Historic 21-Foot-Wide Gem in the Heart of the Upper West Side: Nestled in the heart of the Upper West Side on a tree-lined museum block, this 21-foot-wide, five-story, plus full-basement townhouse is a shining example of Renaissance Revival and Romanesque Revival-style architecture. Located within the prestigious Central Park West Historic District, this home is a rare gem that offers versatility, timeless grandeur, and an opportunity to recreate a masterpiece. Built in 1892, this one-time personal residence reflects an era when architectural craftsmanship and attention to detail were paramount. Its façade, adorned with intricate stonework and decorative elements, is a testament to all the best of the Gilded Age. As you step in, you are met with an original preserved central stair that anchors the grand proportions and stunning original details of the home. Formerly configured as a nine-unit apartment building, the property is now fully vacant and partially renovated, offering endless possibilities for transformation. The garden and parlor levels have been reimagined as a four-bedroom, three-and-a-half-bath duplex with direct backyard access, which could be an owner’s duplex. The custom kitchen showcases hand-cut Danby marble, Fisher & Paykel and Bosch appliances, and bespoke cabinetry. All bathrooms were gut-renovated with new plumbing, designer fixtures, and marble and tile finishes. The six upper-floor one-bedroom apartments (third through fifth floors) remain intact with loads of original charm, fireplace mantels, woodwork, moldings, wainscoting, and each refreshed with new paint and refinished floors, offering a clean slate for future customization. Now fully vacant, the home presents a rare opportunity to complete the conversion to a grand single-family residence or reimagine the layout entirely. With conceptual plans already envisioned for a dramatic reinvention that could transfer with the property, this residence offers an extraordinary opportunity to be transformed into a true single-family home. Imagine 6 or 7 levels of refined living connected by a private elevator, complete with multiple entertaining spaces, a gym with sauna, and a glass-enclosed rooftop with dual terraces for outdoor lounging and dining. Thoughtful design elements like a playroom, wine cellar, and multiple dressing rooms elevate the everyday, while the reimagined garden and seamless indoor-outdoor flow create a rare and luxurious lifestyle in the heart of the city. Situated on one of the most sought-after museum blocks in Manhattan, this townhouse is the embodiment of the Upper West Side landscape. This vibrant and desirable neighborhood features world-class restaurants and cafés, cultural institutions, and Central Park just a stone's throw away. Priced to sell, with willing, ready, and able sellers, do not miss your chance to own a piece of history and be the steward who shepherds the home into its next life!
