Introducing Penthouse 2A at One Harbor Shore. Transcending a residence, it’s a trophy asset for the most discerning collector. Panoramic vistas of the harbor and coastline become art. From breathtaking sunrises over the horizon to the repose of the marina below, PH2A is a sanctuary shaped by serenity, unrivaled quality, and pedigree. Design and scale converge with a sophisticated palette under soaring ceilings. Curated natural stones, oak cabinetry, and flooring all crafted in Italy blend timeless elegance with a contemporary edge. A 170 sq.ft. terrace seamlessly connects the expansive living area to the outdoors, a captivating perch for quiet moments and entertaining alike. Appointed with integrated Sub-Zero and Wolf appliances, a 102-bottle wine chiller, and an 11’ Calacatta Lux quartzite island, the striking kitchen is as functional as it is part of the décor. Open your eyes to the revitalizing sight of morning sun shimmering on the water. Graciously scaled, the primary suite is a tranquil retreat with his-and-hers spa-like marble baths, walk-in wardrobe, and harbor views from the bed pillows. Waterscapes continue into the versatile and oversized den, a distinguished home office space. The pièce de resistance of this home is the 817 sq.ft. rooftop terrace with a fully-equipped kitchen—an oasis crowning Seaport’s most distinctive architectural statement. 42 linear feet of harbor frontage, open air, and blue skies overhead, reveled in from this extraordinary private observation deck. A grand lobby welcomes you home, supplemented by a state-of-the-art amenity suite. Prioritize self-care in the nearly 2,000 sq.ft. fitness center with Pilates reformers, and the restorative wellness room with cold plunge, infrared sauna, and Vitamin C shower. Enjoy a fun reprieve in the elevated game room with a simulator, billiards, and TV lounge, or bring an aperitif to the rooftop lounge and watch the sunset over the city skyline by the fireplace. One Harbor Shore is Seaport’s premier full service address completing the prestigious Fan Pier neighborhood, brought to you by The Fallon Company—the celebrated visionaries behind Boston’s most preeminent waterfront development.
