A truly rare opportunity to reimagine nearly 3,000 SF on an entire floor in Boston's Leather District, just one block from South Station. Units 4A and 4B are being offered together for the first time since 1979, creating the opportunity to transform this expansive footprint into something entirely your own. The 2,052 SF 4B offers a remarkable blank canvas with newly refinished hardwood floors, an open floor plan, and the scale to create a spectacular single-level loft, or thoughtfully reconfigure the space with a dream kitchen, bathroom oasis, multiple living areas, and additional potential bedrooms. The fourth floor also has roof rights for an approximately 300 SF deck on the south side of the roof. Alternatively, the two units could remain separate, with 4A providing immediate rental income at $2,600/month. Mixed-use zoning adds further flexibility for a live/work concept, creative studio, or professional use. Offered well below the current assessed value, the pricing reflects the opportunity to add value through renovation and represents a significant discount to comparable neighborhood pricing. A freight elevator opens directly into 4B for deliveries and moving; it is not a passenger elevator, and stairs are required to access the 4th floor. The building also features a 2026 roof and newer gas-fired heat serves both units. An exceptional opportunity to create a truly one-of-a-kind property in one of Boston's most connected neighborhoods.
