Ready for more space, but not ready to give up South Boston? This sun-filled, sophisticated penthouse duplex offers the kind of space, privacy and convenience that make city living feel effortless. Nearly 2,000 square feet unfolds over two levels, delivering a true single-family home feel with a thoughtfully designed layout that naturally separates the open living spaces from the private bedrooms above. The main level features a spacious, open floor plan with distinct kitchen, dining and living areas. At the center is a well-appointed kitchen with quartz countertops, stainless steel appliances, including a six-burner stovetop, and a substantial island with seating. There's plenty of room for a full dining table and generous living area, while a pantry, half bath and sliders to a private deck complete the level. Upstairs, the primary suite offers an en suite bath with a double vanity and oversized tiled shower, a private deck, and additional flexible space for a home office. Two more well-proportioned bedrooms share a full Jack-and-Jill bath, with a full-size washer and dryer conveniently located on the bedroom level. Ample closet space throughout gives everything a place. Hardwood floors, recessed lighting and central air continue throughout the home. Deeded roof rights offer the opportunity to create a private roof deck, adding another dimension to the home's outdoor space. An owned solar energy system adds long-term value, with no solar loan or lease to assume, warranties that stay with the system, and the benefit of reduced electricity costs through solar generation and Massachusetts incentive programs. A deeded garage parking space on the ground level completes the package. All of it in the heart of South Boston, with neighborhood restaurants, shops and public transportation within walking distance.
