Forecaster 121 is a boutique-style luxury condominium at 121 Portland Street in Boston's West End, within the Bulfinch Triangle. Built as new construction in 2016–2017, the 80-unit building blends historic loft-inspired details with modern finishes. Over the last 12 months, three sales closed at a median price of $900,000, averaging $956 per square foot and 99 days on market, with monthly HOA fees ranging from roughly $475.92 to $1,186.80.
The building offers a range of floorplans centered on one- and two-bedroom homes. One-bedroom residences typically feature open, L-shaped kitchens with counter dining, en suite master baths, and walk-in closets. A popular variation is the "1+S" or one-bedroom-plus-study configuration, where an 11.5' x 10' or 12' x 9' bonus room with its own full or half bath functions as a home office, media room, or guest suite—many of these homes carry 1.5 or 2 full bathrooms.
Two-bedroom, two-bath units offer split-bedroom layouts, open living/dining areas, and floor-to-ceiling glass; one measured 1,247 square feet. Upper-floor homes on the 7th and 9th floors showcase Boston Harbor and downtown views, and penthouse residences add expansive private roof decks—some with dual walk-out access and unobstructed city views. Private terraces appear on multiple units, marketed as outdoor "back yards" seven stories above the city.
The building sits at the intersection of the North End, Beacon Hill, and Faneuil Hall, at the edge of the Rose Kennedy Greenway. Residents are steps from downtown dining, shopping, and open green space, with the historic charm of the surrounding neighborhoods paired with the convenience of a central downtown address. The Bulfinch Triangle location places the T, North Station, and the waterfront within an easy walk, making it well-suited to professionals seeking a low-maintenance urban home.
