Introducing The Grand Penthouse at The St. Regis

Experience a new echelon of luxury living at The Grand Penthouse, the crown jewel of the St. Regis Residences, Boston. Encompassing over 10,000 square feet across two dramatic levels, this one-of-a-kind home sits atop Boston’s iconic Seaport, offering panoramic views of Boston Harbor and the city skyline through soaring floor-to-ceiling windows.

Designed with extraordinary attention to detail, the residence features a double-height great room, a sculptural curved staircase with glass railings, and a grand foyer with an Italian marble radial inlay floor. The kitchen is a masterpiece of form and function, outfitted with Stevali cabinetry, Wolf and Sub-Zero appliances, and a sleek, modern aesthetic. Oak-engineered Slim 180 hardwood floors run throughout the bedrooms and upper levels, while the primary suite offers a sanctuary of its own—complete with dual bathrooms, two walk-in closets, and a private lounge.

Designed for both comfort and function, the home includes six bedrooms, eight full and two half bathrooms, a home office, gym, and a playroom. Every element is curated for refined living and entertaining at scale.

The outdoor living experience is equally extraordinary, with more than 1,000 square feet of private space including two balconies and an expansive rooftop terrace. Highlights include a custom infinity-edge pool with a clear acrylic bottom, an outdoor kitchen with Wolf and Sub-Zero appliances, a natural gas Acucraft fireplace, a retractable Libart International glass roof, and sweeping water views from every angle.

Residents of the St. Regis enjoy access to over 12,000 square feet of world-class amenities, including a luxury swimming pool, jacuzzi, sauna, steam room, spa, state-of-the-art fitness center, HD multi-sport simulator, wine vault, library, boardroom, and catering kitchen. St. Regis signature services—such as butler, concierge, and private dining—are available exclusively to residents. Additional perks include two guest suites for visitors, private in-building access to SAVR restaurant, and pet-friendly facilities including a grooming salon and indoor relief area.

Blending the privacy of a custom home with the legendary service of the St. Regis brand, The Grand Penthouse is a truly rare offering—an extraordinary residence that redefines modern luxury in the heart of Boston.
