A long, easy-access driveway with additional parking welcomes you to this serene and versatile property that perfectly blends privacy, space, and potential. Step through the grand entry and admire the Hacienda-style architecture with crown molding and large Spanish tiles that flow seamlessly throughout the home and extend to the outdoor living spaces, creating a timeless blend of indoor and outdoor elegance. The formal dining room with tray ceiling and dry-bar pass-through to the kitchen creates an ideal space for entertaining, while the living room's cozy fireplace sets the tone for relaxed evenings. The open-concept kitchen is the heart of the home—featuring a wrap-around bar counter, center island, granite countertops, stainless steel appliances, a 5-burner gas stove, and a large walk-in pantry. The kitchen flows effortlessly into the breakfast nook and living area, with direct access to the private fenced patio—an intimate retreat adorned with Spanish-tile patio and a covered awning. Privately situated in its own corner wing of the home, the primary suite is a true sanctuary. This spacious retreat offers tray ceilings, patio access through sliding glass doors, and a grand walk-in closet. The spa-inspired ensuite features dual sinks, a dedicated vanity area, soaking tub, and walk-in shower—creating the perfect space to unwind and indulge in luxury at day's end. Additional highlights include a guest bath with bidet, dedicated laundry area, and an oversized two-car finished garage with a versatile bonus utility/flex room ideal for a studio, creative workspace, or home office. A true standout feature is the separate detached ADU—once the main home—situated on its own private section of the property, ensuring exceptional privacy. The ADU includes 2 bedrooms, a spacious living room with fireplace, kitchen, and bathroom, ready to update or reimagine as guest quarters, rental income, or multi-generational living. Outdoors, the land is a dream: fully irrigated and terraced with multiple graded pads, ideal for horses, gardens, or future expansion. The property is dotted with fruit trees—including lemon, lime, orange, and loquat—along with fragrant angel trumpets and RV hookups for ultimate convenience. This distinctive Morro Hills estate delivers an extraordinary opportunity to live, work, and expand in one of Fallbrook's most picturesque and private settings.
