This stately penthouse at 20 Beacon Street spans 3,787 SqFt across a distinguished 2-level layout w/ 3 bedrooms + 5 total bathrooms. A meticulous 2018 renovation honors the building's 1820 heritage, w/ hand-cast ceiling moldings echoing the original facade and refined herringbone flooring underfoot. Architectural artistry defines the living areas, where Louis XV and Victorian marble mantles serve as sculptural focal points. The master suite unfolds into a serene sanctuary with a bespoke Poliform walk-in closet, a radiant Carrara marble bath with steam shower, soaking tub, and an adjacent custom cedar sauna. Each ensuite bathroom is appointed with warm marble and fixtures exuding timeless refinement. Upstairs, a tailored Poliform bar framed by Art Deco lighting flows onto a terrace envisioned by Winston Flowers-its curated plantings, automated irrigation, and a gas grill define a private oasis above the city. This residence seamlessly fuses architectural legacy with contemporary luxury.
