Three additional bedrooms share a refined hall bath with double vanity, while radiant heated floors, Toto toilets and Hansgrohe fixtures elevate every bath throughout the home. A resort-style backyard with no rear neighbors and layered landscaping creates a private retreat. A refinished PebbleTec pool with all-new equipment serves as the centerpiece, surrounded by travertine patio spaces. Completing the home is a spacious two-car garage with new garage door and motor, EV charger, and upgraded sprinkler systems servicing the front and side yards.
