The rear kitchen layout provides expansive counter space for meal prep along with a three-burner range and 24" oven.

Comfortable theater seating and a hide-a-bed sofa are positioned across from the entertainment center with a 50" TV, making it easy to unwind or host overnight guests.

Toward the front, the master suite features a king bed slide with USB ports, along with a dresser for storage. The front bathroom includes dual sinks, a one-piece fiberglass shower, and a spacious walk-in bathroom closet with shelves and hanging rods. A unique middle utility room with washer and dryer prep, counter space, and a hanging rod offers additional storage or a fully functional laundry area.
