About This Home
If there was an award for the prettiest street in Andover, William Street would take top prize! This special neighborhood known as the "Brick Shawsheen" has beautiful brick homes, a long charming cul de sac street, with sidewalks on both sides, gas lanterns, & friendly neighbors out & about. Love older homes? What you will love here. 1. Amazing curb appeal, full brick home with slate roof. 2. Step inside the foyer, you won't know where to look first, class, charm & grace is everywhere. 3 There are 2 fireplaces, wood burning in the living room & gas (converted from wood) in family room. 4. A perfect floor plan for entertaining, includes a 4 season sunroom, with access to a private patio off the sunroom & family room. 5. There's a 5th bedroom or bonus room with private full bath on the 3rd floor. There's an oversized 2 car detached garage, a brand new 200 amp electrical service, a new boiler, & so much more! An unhurried lifestyle, it feels like the good old days are back. Pure delight!
