Driving Directions

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. A true centerpiece is the remarkable 1,500+-square-foot private terrace, among the largest private outdoor spaces associated with a South End condominium residence. Designed as a seamless extension of the interior, this exceptional outdoor retreat features multiple lounge and dining areas, a Wolf outdoor kitchen with grill, custom marble fireplace, and dedicated wellness space. 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. The Quinn complements the residence with full-service amenities including 24-hour concierge and doorman services, residents' lounge, fitness and wellness facilities, beautiful common spaces, on-site management, secure package services, and 3 garage parking spaces. Set within the vibrant Ink Block and SoWa neighborhood, The Quinn is just moments from Boston's premier culinary, cultural, and lifestyle destinations.
