An extraordinary 4-acre estate in Silverleaf's Upper Canyon, this exceptional property offers panoramic views of the McDowell Mountains and Silverleaf Golf Course, surrounded by conservation-area open space. Encompassing approximately 19,257 livable sq. ft. and 41,446 sq. ft. under roof, the property was conceived by RN Interior Design and Cosan Studio and crafted by Sommer Custom Homes with an emphasis on exceptional entertaining, privacy and highly customized living. One of the estate's most remarkable features is its 27-car garage configuration, including a 4-car main-level garage and a 23-car lower-level climate-controlled show garage, with capacity for up to 54 vehicles when lifts are utilized. Designed with the collector in mind, the lower level includes a car display turntable, specialized car lift with a glass display cube visible from the main-level exercise and lounge areas, media/lounge area, bar, bathroom, elevator and stair access, storage and windows overlooking the Silverleaf community. The scale and design of the lower level extend well beyond automotive storage. Its walk-out basement configuration provides convenient level-on-grade drive-in access, natural light and a highly adaptable environment for private gatherings, charity events, court-style sports such as pickleball or field hockey, and a variety of recreational or entertainment uses. Portions of the space could also be configured for a bowling alley, shooting range or other specialized amenities, offering an uncommon opportunity to tailor the space to individual interests and lifestyle. Inside the main residence, six full bedroom suites and 12 bathrooms are complemented by a great room, bar, theater, office with fireplace, expansive exercise room with access to a covered patio, secondary family room, upper-level recreation room with fireplace and bar, sitting room/library and multiple indoor and outdoor entertaining areas. The primary suite and other living spaces feature extensive custom cabinetry, with multiple laundry areas thoughtfully positioned throughout the estate for convenience and functionality. Steel-and-glass floating staircases, an elevator, fireplaces wrapped in slabs of stone, wood ceilings, backlit stone, wood flooring, Lutron lighting, automated shades and 25 automated doors reflect the level of detail throughout. The culinary spaces are equally considered, with a main kitchen complemented by a concealed second chef's kitchen with commercial appliances, ideal for catering and large gatherings. A food-tray lift connects the secondary kitchen to the upper-level entertainment area. Covered patios and two covered ramadas with fire features extend the living spaces outdoors and create additional areas for entertaining. Behind the scenes, the estate is supported by three-phase power, natural-gas tankless water heaters, spray-foam insulation, a solar energy system and backup generator. Eggersmann cabinetry is incorporated into the kitchen, bar and primary bedroom closets, complemented by integrated lighting and automated shade systems. Set within Silverleaf, a renowned guard-gated community in North Scottsdale, the property offers access to private club amenities and the renowned Tom Weiskopf-designed Silverleaf Golf Course. The combination of expansive acreage, thoughtful architecture, extensive amenities, and a highly versatile lower level creates an exceptional opportunity within the community.
