Making its market debut, this extraordinary custom estate offers approximately 10,790 square feet of refined living space on 2.5 private, level, and fully usable acres in the heart of Granite Bay. Tucked behind a private gate within an exclusive enclave of just four homes, this remarkable residence combines grand scale with a highly functional floor plan that lives primarily like a single-story. The main level features a luxurious primary retreat with a sitting area, fireplaces in both the bedroom and bathroom, direct outdoor access, private sauna, and in-suite washer and dryer. Two additional en suite bedrooms, a dedicated office with full bath, a temperature-controlled 1,000+ bottle wine room, and an impressive entertainment lounge with a full bar and billiard table complete the main floor. The recently updated chef's kitchen is designed to impress with quartzite countertops, a large center island, dual Sub-Zero refrigerators, a Wolf 8-burner range, double ovens and dishwashers, a spacious walk-in pantry, and butler's pantry. Italian travertine flooring with wood inlay, exceptional custom millwork, and five interior fireplaces create a warm yet sophisticated atmosphere. Large French doors open seamlessly from the family room to the resort-style backyard. Upstairs, one wing offers two bedrooms, a full bath, and loft. The opposite wing features a private theater with seating for 10+, guest bath, and an approximately 1,000-square-foot gym with rubber flooring and private balcony. Designed for entertaining, the grounds showcase a PebbleTec saltwater pool and zero-edge spa, covered outdoor kitchen, alfresco dining, outdoor fireplace, fire pit, putting green, illuminated bocce court, and a meandering stream that flows into a tranquil pond. Additional highlights include a circular driveway, extensive guest parking, seven-car garage with an oversized RV-height bay, abundant storage, and a 116-panel owned solar system. Located just minutes from shopping, parks, and top-rated schools, including Eureka Union School District and Granite Bay High School, and near Granite Bay Golf Club, this is a rare opportunity to own one of Granite Bay's most exceptional estate properties.
