Set behind private gates on over three beautifully landscaped acres in the heart of the Rancho Santa Fe Covenant, 18320 Colina Fuerte is a rare, single-level estate offering effortless luxury, timeless design, and resort-style living. Perfectly positioned along the renowned RSF riding and walking trails, this recently reimagined residence captures the essence of Southern California living at its finest. Spanning nearly 8,000 square feet, the main residence has undergone a complete, high-style transformation. Every detail has been thoughtfully curated — from the all-new custom kitchen and spa-inspired baths to the dual primary closets and the exquisite designer lighting found throughout the home, including fixtures featured in Mr. & Mrs. Smith. Elevated finishes, new wood and porcelain tile flooring, and bespoke details enhance each space. The floorplan offers four en-suite bedrooms, a richly paneled executive office, a luxe theater room, and a versatile bonus room ideal for a playroom, gym, or studio. Two detached structures provide added flexibility: a fully self-contained 600-square-foot guest house perfect for multigenerational living or visiting guests, and a third building currently used as a gym—ideal as a detached office, creative studio, or additional guest quarters. Indoor-outdoor living is seamless and inspired. French doors lead to expansive resort-style grounds, complete with a sparkling pool and spa with cascading water features, an outdoor living and dining pavilion with built-in heaters and a firepit, and a full outdoor kitchen featuring a wood-fired pizza oven. A wide, grassy lawn offers space for play, while mature landscaping, fruit trees, and a charming chicken coop add whimsy and character. Car enthusiasts will appreciate the attached two-car garage outfitted with lifts, providing space for up to four vehicles. Additional enhancements include newly added stone exterior accents, a central vacuum system, dual-pane Andersen windows and doors, and a state-of-the-art X-Tech security system with cameras for ultimate peace of mind. Located in the prestigious Covenant of Rancho Santa Fe, residents enjoy exclusive access to the RSF Golf Club, tennis and pickleball courts, miles of private equestrian and walking trails, the charming Village with its shops and restaurants, and a top-rated K-8 public school — all just minutes from coastal attractions, freeways, and world-class amenities. Turnkey, private, and exquisitely updated, 18320 Colina Fuerte is a rare opportunity to own one of Rancho Santa Fe’s most compelling luxury estates.
