Experience a new echelon of luxury living at The Grand Penthouse, the crown jewel of the St. Regis Residences. Encompassing over 10,000 sq ft across 2 dramatic levels, this one-of-a-kind home sits atop Bostons 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 floating staircase with glass railings, and a grand foyer with an Italian marble radial inlay floor. Every element is curated for refined living and entertaining at scale. The outdoor living experience is equally extraordinary, including a custom infinity-edge pool with a clear acrylic bottom, and a retractable Libart International glass roof, and sweeping water views from every angle. Blending the privacy of a custom home with the legendary service of the St. Regis brand, The Grand Penthouse is a truly rare offering Boston has never seen.
