A mudroom with garage access and a powder room complete the main level. Upstairs, the primary suite is a tranquil sanctuary offering two walk-in closets, a luxurious bath with soaking tub, separate vanities, makeup station, and privacy-glass shower and water closet, plus a dedicated office and serene views. Four additional ensuite bedrooms, a bonus room, and a custom-outfitted laundry room complete the second floor.
