The property has significant potential for expansion, including opening a full-time venture or adding a café. The adjacent Mill House features traditional elegance, with spacious rooms, high ceilings, and beautifully landscaped gardens. The property also includes a loft-style penthouse with character and charm, two workshops, a garden, and ample parking. With its rich history and prime location, this property is a unique chance to own a piece of Boston's heritage.
