Looking for the space and feel of a single-family home without leaving South Boston? This sun-filled penthouse duplex offers a compelling alternative, with nearly 2,000 square feet across two levels, generous living spaces, and the privacy and flexibility of a home that truly lets you spread out. Built in 2017, the open main level brings together a beautifully appointed kitchen, spacious dining area, and inviting living room—ideal for everyday living and entertaining. A large kitchen island provides plenty of room to prep, gather, and connect, while hardwood floors and abundant natural light add warmth throughout. Upstairs, the separate bedroom level creates a welcome sense of retreat. The spacious primary suite offers room to unwind, while two additional bedrooms provide flexibility for guests, a dedicated home office, or changing needs. Generous closets and additional storage help keep everything organized. Enjoy morning coffee or evening downtime on your private deck, with deeded roof rights offering the potential to create a future private roof deck, subject to approvals. Garage parking, central air, and in-unit laundry bring welcome convenience to city living. Another standout advantage: the solar system is fully owned, with no solar loan or lease to assume. According to the seller, 2025 electric bills averaged approximately $12 per month, including several $0 months, while SMART solar incentive benefits averaged approximately $37 per month. Future bills, credits, incentives, and eligibility will vary; remaining applicable solar warranties stay with the equipment. Located on South Boston's West Side near neighborhood restaurants, cafés, shops, and public transportation, this condo delivers the room and separation buyers often seek in a single-family home—with the convenience of penthouse living.
