Set atop two meticulously restored turn-of-the-century industrial buildings in the heart of Old City, this trophy duplex is the kind of home that makes everything else feel like a compromise. With 3,556 square feet of interior living space and 1,267 square feet across two private terraces, PH-2 delivers a standard of space, light, and craftsmanship rarely found anywhere in the city. The living level opens directly to a terrace overlooking Arch Street, where sweeping southern views of the skyline become part of daily life. The kitchen, designed by Idea Group and Record e Cucine, is a work of precision — custom Italian cabinetry, Wolf range, built-in coffee system, Sub-Zero refrigeration and wine preservation, and an Asko dishwasher. Every detail was chosen without compromise. A custom white oak staircase ascends to the private upper level, where the primary suite occupies its own world — entirely separated from the secondary bedrooms, with a dedicated private terrace, two Pianca walk-in closet systems, and a five-fixture en-suite bath with radiant heat flooring and soaking tub. The Benjamin Franklin Bridge frames the view. The quiet is complete. Completed in 2022, 115 Arch Street was designed for those who know exactly what they want — and refuse to settle for less. Deeded parking, private storage, smart virtual intercom access, and cold lobby storage complete the offering. 115 Arch Street is a premier conversion of two adjacent industrial buildings. In a testament to technological innovation, the property is equipped with a virtual intercom system for remote access. Owners enjoy private automated indoor parking accessed through the rear of the building. For added convenience, cold storage is available in the building lobby. This residence offers the significant advantage of a 7-year tax abatement. Deeded parking on the first floor with a rear garage entry and licensed storage room in the basement. Please note that a second deeded parking space is available at an additional cost off site.
