**NEW CONSTRUCTION 2026 at 185 E Street.** Unit 3 is an expansive upper duplex offering approximately 1,852 SF of living space across two levels, with 4 bedrooms, 3.5 bathrooms and 2 heated garage (compact) parking spaces. The additional scale is immediately apparent in the proportions of the rooms, creating a home that feels open, balanced and remarkably comfortable across both levels.The main level is centered around an open galley-style kitchen designed to keep the cook connected to the living and dining spaces. Just off the living room is a charming dining nook that works equally well for breakfast, dinner or casual entertaining. The living area features an electric fireplace framed by custom white oak built-in cabinetry, adding warmth, storage and a strong architectural focal point. An integrated balcony extends the living space outdoors, while a generously sized pantry beneath the staircase and a beautifully finished powder room add everyday practicality. Also on the main level is the first of two generously sized en-suite bedrooms, offering the flexibility to function as a primary suite, guest room or private retreat. Upstairs are three additional bedrooms, including a king-sized en-suite with a large walk-out balcony and a beautifully finished bath featuring custom white oak cabinetry and a glass shower enclosure. Two additional bedrooms share a full bath with tub, creating a thoughtful separation between private sleeping spaces and the main living level. Wide-plank white oak flooring, warm modern finishes, custom millwork and all-electric ground-up construction complete this distinctive residence. As one of the building's two upper duplex penthouses, Unit 3 also includes deeded roof rights with spectacular views of the Boston skyline-an exceptional opportunity to create a private rooftop retreat above the city. Located in South Boston's Cityside neighborhood, 185 E Street is just minutes from Tatte, PKL, Castle Island Brewing and the Broadway Red Line, offering a residential setting with easy access to the Seaport, downtown Boston and the rest of the city.
