Introducing the Penthouse at 35 Commonwealth Avenue, one of just two residences in a magnificently renovated brownstone in Back Bay. The Penthouse encompasses the top three levels of the building with the rare opportunity to own over 5,200 square feet with direct elevator access to each floor. It combines three-plus bedrooms and four-and-a-half bathrooms with grandly scaled living, dining and entertaining spaces plus two large walk-out roof decks. This residence has been meticulously constructed with unerring attention to quality; every detail and finish—from the gourmet kitchen to the spa-like marble baths—is top-of-the-line and befitting such a fine address. The Penthouse is complete with two on-site parking spaces (one garage and one outdoor) plus the option to purchase a separate studio residence just off the building’s beautifully appointed lobby, all on the second block of sunny-side Commonwealth Avenue. Square footage includes the Studio in the building.
