About The Claflin

The Claflin
The Claflin Building, situated in the heart of Beacon Hill just across from the iconic State House, has been transformed into a five-unit luxury condo development. Originally built in 1873, converted to condominiums in 1980, and meticulously renovated in 2007, The Claflin now stands as a pinnacle of sophistication in one of Boston's most coveted locations. Boasting exquisite pre-war details, such as remarkably high ceilings and custom moldings, each residence occupies an entire floor and provides direct elevator access.

Crafted by the renowned Cambridge-based Designers America Dural, the condos feature elegant custom kitchens, four fireplaces, and spacious floor-through floor plans. Natural light floods the interiors, accentuating the picturesque views of the State House visible from every residence. The Claflin offers more than just luxury living; it provides an ideal Beacon Hill lifestyle with proximity to Boston Common, Charles Street's shopping and dining, and easy access to the vibrant Midtown neighborhood. Additionally, the convenience of garage rental parking adds the final touch to the allure of The Claflin, making it a premier address in Boston's real estate landscape.
