Step into a unique opportunity on vibrant South Street. This expansive, grandfathered four-story brick-front building offers over 2,900 square feet of combined residential and commercial space in one of the city's most sought-after locations, bordering Rittenhouse Square and Graduate Hospital. Fully tenant-occupied, the mixed-use property includes a ground-floor retail space, a second-floor one-bedroom apartment, and a spacious bi-level two-bedroom apartment spanning the third and fourth floors. The storefront features its own private entrance, separate from the residential units, and enjoys prime positioning along South Street. A large bay window provides excellent visibility and display potential, while the interior boasts high ceilings, a private office, a powder room, and access to a small rear yard. A full basement, accessible from both the store and the street via Bilco doors, adds valuable storage and functionality. Above, the residential units are bright and thoughtfully designed. The second-floor one-bedroom apartment includes hardwood floors and a private rear balcony. The upper bi-level unit offers a more expansive layout with two bedrooms, hardwood flooring, skylight, and access to a large private deck. Both apartments, along with the retail space, are equipped with separate central air conditioning systems that are only a few years old. Originally custom-rehabbed in the 1980s by an architect, the property was designed to maximize natural light throughout. This attention to detail is evident even in the shared staircase, where exposed brick and abundant natural light create a warm, inviting transition between levels. Each unit also includes additional storage space for added convenience. Located just steps from the historic Royal Theatre and surrounded by an eclectic mix of restaurants, shops, theaters, and neighborhood amenities, this one-of-a-kind property offers immediate access to Rittenhouse Square, Graduate Hospital, and Broad Street.
