A wall of windows overlooks the heated pool/spa, covered patio, and expansive backyard framed by mature trees. Inside are 5 bedrooms, including a first-floor secondary bedroom with direct access to a full bath, plus a formal dining room with flexible use options, a formal living room ideal for a home office, and a spacious mudroom off the kitchen with ample storage.
