Introducing the penthouse duplex you've been waiting for on one of the South End's most coveted tree-lined squares. Enter into the open-concept living level, where oversized bay windows frame picturesque views of Rutland Square and custom built-ins flank a gas fireplace, creating a warm and inviting living space. The kitchen is appointed with granite countertops, stainless steel appliances, custom cherry cabinetry, and a convenient breakfast bar, opening seamlessly to a generous dining area and a versatile flex space ideal for a home office or additional sitting room. Just off the dining area, the first of two private outdoor spaces offers effortless indoor-outdoor living. Upstairs, a front-facing primary suite features a walk-in closet and spa-like en-suite bath, joined by two additional generously sized bedrooms, a second full bath, and in-unit laundry. A full staircase leads to a private roof deck with spectacular city views, and a full parking space directly behind the building completes this exceptional offering.
