Set on a professionally landscaped .51-acre property in the heart of Northport, this five bedroom and three and half bath residence spans three full living levels and showcases impeccable architectural detail at every turn. A rocking-chair front porch, turret and portico detailing, Belgian block driveway, copper gutters and roof ridges, and a historically curated seven-color Victorian exterior create unforgettable curb appeal.
