Rising above the South End, this one-of-a-kind 3-bedroom plus den, 2.5-bath penthouse offers exceptional scale, privacy, and indoor-outdoor living. The residence spans 2,808 square feet inside and more than 2,400 square feet of exterior space, including a landscaped Brazilian Ipe terrace and a newly completed upper roof deck. Landmark-protected skyline views provide a remarkable backdrop for entertaining, relaxing, and enjoying the city from above. Inside, soaring 18+ foot ceilings, dramatic natural light, and a gas fireplace create a sense of volume rarely found in Boston. The bespoke renovation pairs beauty with functionality through Italian Pantano marble, Hestan and Miele appliances, Nanz hardware, hand-painted wallcoverings, and custom vintage teak built-ins. Thoughtfully integrated technology includes fully automated Lutron shades, discreet in-wall speakers throughout, radiant heated floors, and a dedicated theater with 5.1 surround sound. A sound-insulated primary suite provides exceptional privacy, while temperature-controlled wine storage, a home gym, a custom 500-pound Krieger entry door, and parking approved for EV-charger installation complete the offering. Far removed from conventional new construction, this is one of the South End's most distinctive penthouses-a private urban retreat with more than 5,200 square feet of combined interior and exterior space.
