Behind the private gates of Rancho Glen Estates sits this rare single-level estate on 1.57 acres, one of Carmel Valley's largest and most private lots. At 3,841 square feet, the open floor plan impresses immediately with soaring exposed wood beam ceilings and a fresh, clean palette throughout following a full interior paint. The layout flows effortlessly and features multiple flex spaces that function perfectly as a four-bedroom home with dedicated office areas, giving every member of the household room to spread out and live comfortably. The 1.57-acre lot is the real story here. There is ample room to add a resort-style pool, regulation sport court, detached ADU for guests or multigenerational living, and extensive outdoor entertaining areas, all while maintaining the kind of privacy and open space that is nearly impossible to find in this market. A three-car garage and owned solar round out the practical side of this property, delivering both everyday convenience and meaningful long-term energy savings. Situated in the heart of one of San Diego's most sought-after school corridors, this home is zoned for Pacific Sky Elementary and Pacific Trails Middle School, with highly regarded high school options nearby rounding out an exceptional education profile. Gated. Private. Expansive. A property of this caliber and lot size rarely comes to market!
