Residence 12J at The Quinn presents an extraordinary combination of architectural distinction, refined interiors, and expansive private outdoor living in the heart of Boston’s South End. This spectacular 4 bed / 4.5 bath corner home is defined by exceptional craftsmanship, sophisticated design, and sweeping views through floor-to-ceiling glass across the South End, Back Bay skyline, and downtown Boston.

Whether enjoying a quiet morning, intimate dinner, or entertaining beneath the Boston skyline, the terrace delivers a remarkable level of privacy, scale, and indoor-outdoor living rarely found in the city. Inside, the gracious great room flows into a beautifully appointed chef’s kitchen anchored by a striking Calcutta marble island. Custom cabinetry, dual Wolf ovens, Sub-Zero refrigeration, wine storage, and integrated appliances combine performance with refined contemporary design. The serene primary suite offers skyline views, sophisticated Poliform wardrobes enhanced by California Closets, radiant-heated marble floors, and a sumptuous spa-inspired bath. 3 additional bedrooms feature en-suite baths, while a custom den with oak built-ins and dedicated climate control offers a versatile home office, library, or media room. Throughout, designer wall coverings, bespoke millwork, Lutron shades, Bang & Olufsen technology, and curated finishes showcase an extraordinary level of craftsmanship.
