About this home
This exceptional penthouse duplex seamlessly blends the timeless elegance of Back Bay architecture with the comfort and sophistication of modern living. Offering direct elevator access to both levels, the residence encompasses over 3,000 square feet of thoughtfully designed living space. The upper level unfolds as a bright, open living and entertaining space highlighted by soaring ceilings, a fireplaced living room, a skylit dining area, and a beautifully appointed custom kitchen, with a full bath conveniently located on the same level. Oversized glass doors open directly onto a private walk-out deck, creating effortless indoor-outdoor living, while a separate private roof deck offers sweeping Boston skyline views. The lower level features three spacious bedrooms, two full bathrooms, and a versatile lounge framed by custom built-ins, creating a flexible space for a family room or home office. Additional highlights include two deeded parking spaces and a pet-friendly association.
