The Cadwalader House is an extraordinary trophy property in the heart of Philadelphia’s historic Society Hill, offering a once-in-a-generation opportunity to create one of the city’s most remarkable private residences. Ideally situated just steps from Washington Square and surrounded by the architecture, charm, and character that define this coveted neighborhood, the property is equally close to some of Philadelphia’s finest restaurants, cafés, shops, and cultural attractions, including Zahav, Talula’s Garden, Fork, Headhouse Square, the Museum of the American Revolution, Independence Hall, and the Delaware River waterfront. Encompassing more than 10,000 square feet across five floors, the residence offers a scale and configuration rarely found in Center City, with a private elevator, expansive and highly flexible floor plan, and 3-CAR PARKING, an exceptionally rare amenity in Society Hill. The property is zoned exclusively for single-family residential use. Importantly, the exterior restoration and roof have already been completed, allowing the next owner to focus entirely on the interior transformation. Bring your own architect and vision, or utilize the existing architectural plans for a proposed seven-bedroom, six-full-bath residence with two powder rooms. With the major exterior work complete, the property is ready for interior construction and customization. Combining historic significance, extraordinary scale, coveted 3-CAR PARKING, an elevator, and an unparalleled Society Hill location, The Cadwalader House presents an exceptional opportunity to create a truly one-of-a-kind Philadelphia residence. Please note that many of the photographs included in this listing are renderings depicting what the completed residence could look like.
