If you are looking for a home with classic elegance, located in the heart of downtown Andover, this stunning home should be on your list! Built in 1897 by Ovid Chapman, the first occupants were members of a Phillips Academy Secret Society, who named the grand style home "Sphinx House" and added a lions head to the stonework on the front porch which is still there today! The home was thoughtfully renovated, updated and expanded in 2003, preserving the unique architectural details and creating a floor plan that is practical and flows gracefully. The first floor offers a fireplaced living room, sitting room, family room with wet bar, Black Dog kitchen, elegant dining room and home office. The second floor has 3 large bedrooms, 2 full baths, laundry and a Master Suite with custom walk-in closet and spa-like bath. Lower level has a game room with half bath. The Carriage House (1986) offers a finished 2nd floor with full bath, office and heated 3 car garage, a very rare "in-town" find!
