Behind private gates at the end of a long, secluded drive lies one of Big Sky’s most exceptional custom estates – a residence where timeless architecture, resort-inspired amenities, and uncompromising craftsmanship come together on approximately 2.1 private acres. Purposefully designed and owner-built with no expense spared, this rare single-story estate offers an extraordinary opportunity to own one of Simi Valley’s finest luxury properties. Spanning approximately 6,400 sq, ft., the home was designed to celebrate California’s coveted indoor-outdoor lifestyle. Two expansive pocket sliding glass doors dissolve the boundaries between the interior and the spectacular grounds beyond, allowing every gathering to flow effortlessly from elegant living spaces to world-class outdoor entertaining. Rich hardwood floors, soaring beamed ceilings, and a dramatic double-sided fireplace create warmth and sophistication throughout the open-concept design. The living room, dining room, family room, gourmet kitchen, and luxurious primary suite all enjoy sweeping views of the resort-style backyard. At the heart of the home, the chef’s kitchen is both beautiful and functional, featuring handcrafted custom cabinetry, an oversized island, walk-in pantry, butler’s pantry with coffee station, Miele professional range, Sub-Zero refrigerator, dual dishwashers, convection oven, warming drawer, wine refrigerator, pot filler, and premium appliances worthy of the most discerning culinary enthusiast. The family room offers theater style seating, viewing screen, and a full wet bar, creating the perfect setting for movie nights or game-day entertaining. The private primary retreat rivals a luxury resort, offering its own sitting room with fireplace and wet bar, a tranquil bedroom opening to a secluded patio, and separate spa-inspired bathrooms and expansive custom walk-in closets designed for both him and her. Each of the home’s five bedrooms enjoys its own beautifully appointed en-suite bath, while two thoughtfully positioned laundry rooms provide convenience without compromise. Outside, the estate transforms into a private resort unlike anything else in the area. A breathtaking zero-edge pool with Baja shelf and spa serves as the centerpiece, surrounded by multiple lounge areas overlooking panoramic valley, city, and canyon vistas. Every inch of the grounds was curated for recreation and entertaining–from multiple putting greens, pickleball and basketball court, outdoor shower, and two outdoor bathrooms, to multiple destination patios designed for every occasion. The outdoor living experience is second to none. The impressive covered main patio features skylights, dual fire features, and a fully equipped outdoor kitchen complete with a professional BBQ, griddle, side burner, refrigerator, ice maker, dishwasher, sink, and expansive bar seating. Separate Lodge and Mancave patios, each anchored by their own fireplace, create inviting spaces for year-round entertaining, while an additional fire pit lounge offers the perfect place to unwind beneath the stars. Luxury extends well beyond what meets the eye with a Lutron lighting system, whole-home indoor and outdoor audio, three-zone HVAC, Generac backup generator, attached three-car garage, separate two-car garage, oversized motor court, and room for RV parking. Rarely does a property combine the privacy of a secluded estate, the convenience of a coveted single-story floor plan, and the caliber of amenities found in the world’s finest resorts. This is more than a home – it is a destination, a lifestyle, and one of Big Sky’s most remarkable offerings. Opportunities of this significance are truly few and far between.
